+How to publish node-hid
+========================
+
+### newer way (in short) ###
+
+First, make sure version is bumped to new version. (if code change)
+
+Then, on each of MacOSX, Windows, Linux, do:
+```
+git clone https://github.com/node-hid/node-hid.git
+cd node-hid     
+npm run prepublish                # get the hidapi submodule
+npm install --build-from-source   # rebuilds the C code
+node ./src/show-devices.js        # simple tests
+npm run prebuild                  # build all the versions
+npm run prebuild-upload <gh-token> # upload all the versions using github token
+```
+And then on master dev box:
+```
+npm run clean # clean out directory
+npm publish  # update npmjs, be sure to have Authy app for OTP code
+```
+
+remember for Windows
+```
+$env:PYTHON = "$env:USERPROFILE\.windows-build-tools\python27\python.exe"
+```
+
+
+#### notes ####
+- As of Node v10 on Windows, may need to do:
+-- `$env:Path += ";C:\Program Files\Git\mingw64\libexec\git-core
+-- and install git with "make unix tools available to windows command prompt"
+
+#### old way ###
+
+1. Merge all changes and new features into master
+2. Bump up npm version in `package.json`
+3. Update the `README.md` to reference this current version (if needed)
+4. Commit then generate new tags based on package.json version number
+   with e.g. `git tag v0.5.4 -a` and include the change log in the tag's annotation.
+5. Push tags to Github with `git push --tags`
+6. Watch Travis and Appveyor CI builds
+7. Publish to npm after builds finish. Builds can take half an hour and occasionally fail for seemingly no reason. Restart any failures in the travis or appeveyor ui. While you wait, remove the content of the Github release message so the tag's text shows. When the entire matrix succeeds and all binaries exist run `npm publish`.
+
+
+## Config Travis, AppVeyor and Github to generate all of the binaries.
+
+Before we are able to run everything stated above some steps need to be taken. Specifically for being able to publish the pre compiled binaries to Github. The correct keys need to be setup in the `travis.yml` and `appveyor.yml` files. For Travis, this needs to be done by the admin of the Github repo. For AppVeyor, this will need to be done by the owner of the AppVeyor account.
+
+### Setting up secure keys in Travis.
+
+Setting up the keys in Travis is easy if you have Ruby and Rubygems installed and working then run:
+
+`gem install travis`
+
+After the Travis gem is installed run the following command for each of the required keys:
+
+`travis encrypt SOMEVAR=secretvalue`
+
+And substitute the values in the `.travis.yml` file for the new ones. Detailed instructions can
+be found here: http://docs.travis-ci.com/user/environment-variables/#Secure-Variables
+
+### Setting up secure keys in AppVeyor
+
+It is even easier than Travis to configure AppVeyor. You do not need to install anything, just go to your account and click on `encrypt tool`. Enter the values in the input field and click "Encrypt". In the same way as we do for Travis, we then need to substitute the newly generated values for the old ones.
+
+Detailed instructions can be found here: http://www.appveyor.com/docs/build-configuration#secure-variables
+

+
+## Hand publish method using `node-pre-gyp-github`
+* Install tools globally to make things easier:
+```
+npm install -g node-pre-gyp
+npm install -g node-pre-gyp-github
+npm install -g rimraf
+```
+* Checkout clean node-hid:
+```
+rm -rf node-hid
+git clone https://github.com/node-hid/node-hid.git
+cd node-hid
+npm run prepublish
+```
+
+* Clean checkout before each build:
+```
+npm run clean
+npm install
+```
+
+* Do simple sanity tests
+```
+node ./src/show-devices.js
+node ./src/test-blink1.js
+```
+
+* Test out node-pre-gyp packaging and publish draft:
+```
+node-pre-gyp configure
+node-pre-gyp build
+node-pre-gyp package
+node-pre-gyp-github publish
+```
+
+* Do the above for each version of node:
+  * v6.9.1 LTS
+  * v4.6.2 LTS
+  * v0.12.17
+
+
+### Windows notes:
+* Using nvm-windows, install each version of node needed (32-bit & 64-bit):
+```
+nvm install v0.12.7 32
+nvm install v0.12.7 64
+nvm install v4.6.2 32
+nvm install v4.6.2 64
+nvm install v6.9.1 32
+nvm install v6.9.1 64
+```
+
+* Then, before each build:
+```
+nvm use v0.12.7 32
+node install -g node-pre-gyp
+node install -g node-pre-gyp-github
+node install -g rimraf
+npm run clean
+npm install
+
+```
+
+
+
+## Old publish method
+
+(cribbed from node-serialport)
+
+## Setup for Linux, Windows and OSX
+
+1. Merge all changes and new features into master.
+2. Fill out changelog.md.
+3. Bump up npm version *AND* binary host version in `package.json`, commit and push.
+4. Update the README.md to reference this current version and to previous major version docs.
+5. Generate new tags based on package.json version number with `git tag 4.0.0 -a` and include the change log in the tag's annotation.
+6. Push tags to Github with `git push --tags`
+7. Switch to node v0.12 and npm 2
+8. `rm -rf node_modules build && npm install`
+9. Publish to npm after builds finish. Builds can take half an hour and occasionally fail for seemingly no reason. Restart any failures in the travis or appeveyor ui. While you wait, remove the content of the Github release message so the tag's text shows. When the entire matrix succeeds and all binaries exist run `npm publish`.
+
+Differences for beta release
+* Tag like: `git tag 4.0.1-beta1 -a` and include the change log in the tag's annotation.
+* Publish with `npm publish --tag beta`
+
+
+## Binary Hand-publish Notes
+* On Mac/Linux, have a ~/.node_pre_gyprc with Amazon AWS S3 accessKeyId & secretAccessKey
+* On Windows, put that file in /c/Users/{username} when using MinGW
+
+## Hand-publish steps
+1. Pick node version (e.g. "nvm use v4" or "nodist use v4")
+2. Update node-hid from master: `git pull`
+3. Build: `npm install`
+4. Package using node-pre-gyp: `npm run gyppackage`
+5. Publish to AWS S3 using node-pre-gyp: `npm run gyppublish`
+6. Clean up build products: `npm run clean`

+## Platform Support
+`node-hid` supports Node.js v6 and upwards. For versions before that,
+you will need to build from source. The platforms, architectures and node versions `node-hid` supports are the following.
+In general we try to provide pre-built native library binaries for the most common platforms, Node and Electron versions.
+
+We strive to make `node-hid` cross-platform so there's a good chance any
+combination not listed here will compile and work.
+
+### Supported Platofrms ###
+- Windows x86 (32-bit) (¹)
+- Windows x64 (64-bit)
+- Mac OSX 10.9+
+- Linux x64 (²)
+- Linux x86 (¹)
+- Linux ARM / Raspberry Pi (¹)
+- Linux MIPSel (¹)
+- Linux PPC64 (¹)
+
+¹ prebuilt-binaries not provided for these platforms
+² prebuilt binary built on Ubuntu 16.04 x64
+
+### Supported Node versions ###
+
+* Node v6 to
+* Node v12
+
+### Supported Electron versions ###
+
+* Electron v1 to (³)
+* Electron v5
+
+
+³ Electron v1.8 currently has issues, but prebuilt binaries are provided.
+
+
+## Installation
+
+For most "standard" use cases (node v4.x on mac, linux, windows on a x86 or x64 processor), `node-hid` will install nice and easy with a standard:
+
+```
+npm install node-hid
+```
+
+If you install globally, the test program `src/show-devices.js` is installed as `hid-showdevices`. On Linux you can use it to try the difference between `hidraw` and `libusb` driverTypes:
+```
+$ npm install -g node-hid
+$ hid-showdevices libusb
+$ hid-showdevices hidraw
+```
+
+### Installation Special Cases
+
+We are using [prebuild](https://github.com/mafintosh/prebuild) to compile and post binaries of the library for most common use cases (linux, mac, windows on standard processor platforms). If you are on a special case, `node-hid` will work, but it will compile the binary when you install.
+
+If `node-hid` doesn't have a pre-built binary for your system
+(e.g. Linux on Raspberry Pi),
+`node-gyp` is used to compile `node-hid` locally.  It will need the pre-requisites
+listed in [Compling from source](#compiling-from-source) below.
+
+
+## Examples
+
+In the `src/` directory, various JavaScript programs can be found
+that talk to specific devices in some way.  Some interesting ones:
+- [`show-devices.js`](./src/show-devices.js) - display all HID devices in the system
+- [`test-ps3-rumbleled.js`](./src/test-ps3-rumbleled.js) - Read PS3 joystick and control its LED & rumblers
+- [`test-powermate.js`](./src/test-powermate.js) - Read Griffin PowerMate knob and change its LED
+- [`test-blink1.js`](./src/test-blink1.js) - Fade colors on blink(1) RGB LED
+- [`test-bigredbutton.js`](./src/test-bigredbutton.js) - Read Dreamcheeky Big Red Button
+- [`test-teensyrawhid.js`](./src/test-teensyrawhid.js) - Read/write Teensy running RawHID "Basic" Arduino sketch
+
+To try them out, run them like `node src/showdevices.js` from within the node-hid directory.
+
+----
+
+## Usage
+
+### List all HID devices connected
+
+```js
+var HID = require('node-hid');
+var devices = HID.devices();
+```
+
+`devices` will contain an array of objects, one for each HID device
+available.  Of particular interest are the `vendorId` and
+`productId`, as they uniquely identify a device, and the
+`path`, which is needed to open a particular device.
+
+Sample output:
+
+```js
+HID.devices();
+{ vendorId: 10168,
+    productId: 493,
+    path: 'IOService:/AppleACPIPl...HIDDevice@14210000,0',
+    serialNumber: '20002E8C',
+    manufacturer: 'ThingM',
+    product: 'blink(1) mk2',
+    release: 2,
+    interface: -1,
+    usagePage: 65280,
+    usage: 1 },
+  { vendorId: 1452,
+    productId: 610,
+    path: 'IOService:/AppleACPIPl...Keyboard@14400000,0',
+    serialNumber: '',
+    manufacturer: 'Apple Inc.',
+    product: 'Apple Internal Keyboard / Trackpad',
+    release: 549,
+    interface: -1,
+    usagePage: 1,
+    usage: 6 },
+    <and more>
+```
+
+#### Cost of `HID.devices()` and `new HID.HID()` for detecting device plug/unplug
+Both `HID.devices()` and `new HID.HID()` are relatively costly, each causing a USB (and potentially Bluetooth) enumeration. This takes time and OS resources. Doing either can slow down the read/write that you do in parallel with a device, and cause other USB devices to slow down too. This is how USB works.
+
+If you are polling `HID.devices()` or doing repeated `new HID.HID(vid,pid)` to detect device plug / unplug, consider instead using [node-usb-detection](https://github.com/MadLittleMods/node-usb-detection). `node-usb-detection` uses OS-specific, non-bus enumeration ways to detect device plug / unplug.
+
+### Opening a device
+
+Before a device can be read from or written to, it must be opened.
+The `path` can be determined by a prior HID.devices() call.
+Use either the `path` from the list returned by a prior call to `HID.devices()`:
+
+```js
+var device = new HID.HID(path);
+```
+
+or open the first device matching a VID/PID pair:
+
+```js
+var device = new HID.HID(vid,pid);
+```
+
+The `device` variable will contain a handle to the device.
+If an error occurs opening the device, an exception will be thrown.
+
+A `node-hid` device is an `EventEmitter`.
+While it shares some method names and usage patterns with
+`Readable` and `Writable` streams, it is not a stream and the semantics vary.
+For example, `device.write` does not take encoding or callback args and
+`device.pause` does not do the same thing as `readable.pause`.
+There is also no `pipe` method.
+
+### Picking a device from the device list
+If you need to filter down the `HID.devices()` list, you can use
+standard Javascript array techniques:
+```js
+var devices = HID.devices();
+var deviceInfo = devices.find( function(d) {
+    var isTeensy = d.vendorId===0x16C0 && d.productId===0x0486;
+    return isTeensy && d.usagePage===0xFFAB && d.usage===0x200;
+});
+if( deviceInfo ) {
+  var device = new HID.HID( deviceInfo.path );
+  // ... use device
+}
+```
+
+### Reading from a device
+
+To receive FEATURE reports, use `device.getFeatureReport()`.
+
+To receive INPUT reports, use `device.on("data",...)`.
+A `node-hid` device is an EventEmitter.
+Reading from a device is performed by registering a "data" event handler:
+
+```js
+device.on("data", function(data) {});
+```
+
+You can also listen for errors like this:
+
+```js
+device.on("error", function(err) {});
+```
+For FEATURE reports:
+
+```js
+var buf = device.getFeatureReport(reportId, reportLength)
+```
+
+
+Notes:
+- Reads via `device.on("data")` are asynchronous
+- Reads via `device.getFeatureReport()` are synchronous
+- To remove an event handler, close the device with `device.close()`
+- When there is not yet a data handler or no data handler exists,
+   data is not read at all -- there is no buffer.
+
+### Writing to a device
+
+To send FEATURE reports, use `device.sendFeatureReport()`.
+
+To send OUTPUT reports, use `device.write()`.
+All writing is synchronous.
+
+```js
+device.write([0x00, 0x01, 0x01, 0x05, 0xff, 0xff]);
+```
+```js
+device.sendFeatureReport( [0x01, 'c', 0, 0xff,0x33,0x00, 70,0, 0] );
+```
+Notes:
+- Both `device.write()` and `device.sendFeatureReport()` return number of bytes written
+- Some devices use reportIds for OUTPUT reports.  In that case,
+the first byte of the array to `write()` should be the reportId.
+- BUG: Windows requires the prepend of an extra byte due to a bug in hidapi (see issue #187 and Windows notes below)
+
+
+## Complete API
+
+### `devices = HID.devices()`
+
+- Return array listing all connected HID devices
+
+### `HID.setDriverType(type)`
+  - Linux only
+  - Sets underlying HID driver type
+  - `type` can be `"hidraw"` or `"libusb"`, defaults to `"hidraw"`
+
+### `device = new HID.HID(path)`
+
+- Open a HID device at the specified platform-specific path
+
+### `device = new HID.HID(vid,pid)`
+
+- Open first HID device with specific VendorId and ProductId
+
+### `device.on('data', function(data) {} )`
+
+- `data` - Buffer - the data read from the device
+
+### `device.on('error, function(error) {} )`
+
+- `error` - The error Object emitted
+
+### `device.write(data)`
+
+- `data` - the data to be synchronously written to the device
+- Returns number of bytes actually written
+
+### `device.close()`
+
+- Closes the device. Subsequent reads will raise an error.
+
+### `device.pause()`
+
+- Pauses reading and the emission of `data` events.  
+This means the underlying device is _silenced_ until resumption --
+it is not like pausing a stream, where data continues to accumulate.
+
+### `device.resume()`
+
+- This method will cause the HID device to resume emmitting `data` events.
+If no listeners are registered for the `data` event, data will be lost.
+
+- When a `data` event is registered for this HID device, this method will
+be automatically called.
+
+### `device.read(callback)`
+
+- Low-level function call to initiate an asynchronous read from the device.
+- `callback` is of the form `callback(err, data)`
+
+### `device.readSync()`
+
+- Return an array of numbers data. If an error occurs, an exception will be thrown.
+
+### `device.readTimeout(time_out)`
+
+- `time_out` - timeout in milliseconds
+- Return an array of numbers data. If an error occurs, an exception will be thrown.
+
+### `device.sendFeatureReport(data)`
+
+- `data` - data of HID feature report, with 0th byte being report_id (`[report_id,...]`)
+- Returns number of bytes actually written
+
+### `device.getFeatureReport(report_id, report_length)`
+
+- `report_id` - HID feature report id to get
+- `report_length` - length of report
+
+-----
+
+## Windows notes
+
+### Mice and keyboards
+In general you cannot access USB HID keyboards or mice.  
+The OS owns these devices.
+
+### Xbox 360 Controller on Windows 10
+For reasons similar to mice & keyboards it appears you can't access this controller on Windows 10.
+
+### Prepend byte to `hid_write()`
+Because of a limitation in the underlying `hidapi` library, if you are using `hid_write()` you should prepend a byte to any data buffer, e.g.
+```js
+var device = new HID.HID(vid,pid);
+var buffer = Array(64).fill(0x33); // device has 64-byte report
+if(os.platform === 'win32') {
+  buffer.unshift(0);  // prepend throwaway byte
+}
+```
+
+
+## Linux notes
+
+### Selecting driver type
+
+By default as of `node-hid@0.7.0`, the [hidraw](https://www.kernel.org/doc/Documentation/hid/hidraw.txt) driver is used to talk to HID devices. Before `node-hid@0.7.0`, the more older but less capable [libusb](http://libusb.info/) driver was used.  With `hidraw` Linux apps can now see `usage` and `usagePage` attributes of devices.
+
+If you would still like to use the `libusb` driver, then you can do either:
+```
+npm install node-hid@0.5.7
+```
+or:
+```
+npm install node-hid --build-from-source --driver=libusb
+```
+
+Or during runtime, you can use `HID.setDriverType('libusb')` immediately after require()-ing `node-hid`:
+```js
+var HID = require('node-hid');
+HID.setDriverType('libusb');
+```
+
+
+
+
+### udev device permissions
+Most Linux distros use `udev` to manage access to physical devices,
+and USB HID devices are normally owned by the `root` user.
+To allow non-root access, you must create a udev rule for the device,
+based on the devices vendorId and productId.
+
+This rule is a text file placed in `/etc/udev/rules.d`.  
+
+For an example HID device (say a blink(1) light with vendorId = 0x27b8 and productId = 0x01ed,
+the rules file to support both `hidraw` and `libusb` would look like:
+```
+SUBSYSTEM=="input", GROUP="input", MODE="0666"
+SUBSYSTEM=="usb", ATTRS{idVendor}=="27b8", ATTRS{idProduct}=="01ed", MODE:="666", GROUP="plugdev"
+KERNEL=="hidraw*", ATTRS{idVendor}=="27b8", ATTRS{idProduct}=="01ed", MODE="0666", GROUP="plugdev"
+```
+Note that the values for idVendor and idProduct must be in hex and lower-case.
+
+Save this file as `/etc/udev/rules.d/51-blink1.rules`, unplug the HID device,
+and reload the rules with:
+```
+sudo udevadm control --reload-rules
+```
+
+For a complete example, see the
+[blink1 udev rules](https://github.com/todbot/blink1/blob/master/linux/51-blink1.rules).
+
+
+## Compiling from source
+
+To compile & develop locally or if `prebuild` cannot download a pre-built
+binary for you, you will need the following tools:

+```
+git clone https://github.com/node-hid/node-hid.git
+cd node-hid                                        # must change into node-hid directory
+npm run prepublish                                 # get the needed hidapi submodule
+npm install --build-from-source                    # rebuilds the module with C code
+node ./src/show-devices.js
+```
+
+You will see some warnings from the C compiler as it compiles
+[hidapi](https://github.com/signal11/hidapi) (the underlying C library `node-hid` uses).  
+This is expected.
+
+For ease of development, there are also the scripts:
+```
+npm run gypclean      # "node-gyp clean" clean gyp build directory
+npm run gypconfigure  # "node-gyp configure" configure makefiles
+npm run gypbuild      # "node-gyp build" build native code
+```
+
+## Using `node-hid` in Electron projects
+In your electron project, add `electron-rebuild` to your `devDependencies`.
+Then in your package.json `scripts` add:
+
+```
+  "postinstall": "electron-rebuild --force"
+```
+This will cause `npm` to rebuild `node-hid` for the version of Node that is in Electron.
+If you get an error similar to `The module "HID.node" was compiled against a differnt version of Node.js`
+then `electron-rebuild` hasn't been run and Electron is trying to use `node-hid` not built for it.
+
+If you want a specific version of electron, do something like:
+
+```
+  "postinstall": "electron-rebuild -v 0.36.5 --force -m . -w node-hid"
+```
+
+If using `node-hid` with `webpack`, you may find it useful to list `node-hid` as an external in your `webpack-config.js`:
+```
+  externals: {
+    "node-hid": 'commonjs node-hid'
+  }
+```
+(You can see an example of this in [Blink1Control2](https://github.com/todbot/Blink1Control2/)'s [webpack-config.js](https://github.com/todbot/Blink1Control2/blob/master/webpack.config.js)
+
+## Using `node-hid` in NW.js projects
+(TBD)

+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+         HIDAPI library for Windows, Linux, FreeBSD and Mac OS X
+        =========================================================
+
+About
+======
+
+HIDAPI is a multi-platform library which allows an application to interface
+with USB and Bluetooth HID-Class devices on Windows, Linux, FreeBSD, and Mac
+OS X.  HIDAPI can be either built as a shared library (.so or .dll) or
+can be embedded directly into a target application by adding a single source
+file (per platform) and a single header.
+
+HIDAPI has four back-ends:
+	* Windows (using hid.dll)
+	* Linux/hidraw (using the Kernel's hidraw driver)
+	* Linux/libusb (using libusb-1.0)
+	* FreeBSD (using libusb-1.0)
+	* Mac (using IOHidManager)
+
+On Linux, either the hidraw or the libusb back-end can be used. There are
+tradeoffs, and the functionality supported is slightly different.
+
+Linux/hidraw (linux/hid.c):
+This back-end uses the hidraw interface in the Linux kernel.  While this
+back-end will support both USB and Bluetooth, it has some limitations on
+kernels prior to 2.6.39, including the inability to send or receive feature
+reports.  In addition, it will only communicate with devices which have
+hidraw nodes associated with them.  Keyboards, mice, and some other devices
+which are blacklisted from having hidraw nodes will not work. Fortunately,
+for nearly all the uses of hidraw, this is not a problem.
+
+Linux/FreeBSD/libusb (libusb/hid.c):
+This back-end uses libusb-1.0 to communicate directly to a USB device. This
+back-end will of course not work with Bluetooth devices.
+
+HIDAPI also comes with a Test GUI. The Test GUI is cross-platform and uses
+Fox Toolkit (http://www.fox-toolkit.org).  It will build on every platform
+which HIDAPI supports.  Since it relies on a 3rd party library, building it
+is optional but recommended because it is so useful when debugging hardware.
+
+What Does the API Look Like?
+=============================
+The API provides the the most commonly used HID functions including sending
+and receiving of input, output, and feature reports.  The sample program,
+which communicates with a heavily hacked up version of the Microchip USB
+Generic HID sample looks like this (with error checking removed for

+
+Build Instructions
+===================
+
+This section is long. Don't be put off by this. It's not long because it's
+complicated to build HIDAPI; it's quite the opposite.  This section is long
+because of the flexibility of HIDAPI and the large number of ways in which
+it can be built and used.  You will likely pick a single build method.
+
+HIDAPI can be built in several different ways. If you elect to build a
+shared library, you will need to build it from the HIDAPI source
+distribution.  If you choose instead to embed HIDAPI directly into your
+application, you can skip the building and look at the provided platform
+Makefiles for guidance.  These platform Makefiles are located in linux/
+libusb/ mac/ and windows/ and are called Makefile-manual.  In addition,
+Visual Studio projects are provided.  Even if you're going to embed HIDAPI
+into your project, it is still beneficial to build the example programs.
+
+
+Prerequisites:
+---------------
+
+	Linux:
+	-------
+	On Linux, you will need to install development packages for libudev,
+	libusb and optionally Fox-toolkit (for the test GUI). On
+	Debian/Ubuntu systems these can be installed by running:
+	    sudo apt-get install libudev-dev libusb-1.0-0-dev libfox-1.6-dev
+
+	If you downloaded the source directly from the git repository (using
+	git clone), you'll need Autotools:
+	    sudo apt-get install autotools-dev autoconf automake libtool
+
+	FreeBSD:
+	---------
+	On FreeBSD you will need to install GNU make, libiconv, and
+	optionally Fox-Toolkit (for the test GUI). This is done by running
+	the following:
+	    pkg_add -r gmake libiconv fox16
+
+	If you downloaded the source directly from the git repository (using
+	git clone), you'll need Autotools:
+	    pkg_add -r autotools
+
+	Mac:
+	-----
+	On Mac, you will need to install Fox-Toolkit if you wish to build
+	the Test GUI. There are two ways to do this, and each has a slight
+	complication. Which method you use depends on your use case.
+
+	If you wish to build the Test GUI just for your own testing on your
+	own computer, then the easiest method is to install Fox-Toolkit
+	using ports:
+		sudo port install fox
+
+	If you wish to build the TestGUI app bundle to redistribute to
+	others, you will need to install Fox-toolkit from source.  This is
+	because the version of fox that gets installed using ports uses the
+	ports X11 libraries which are not compatible with the Apple X11
+	libraries.  If you install Fox with ports and then try to distribute
+	your built app bundle, it will simply fail to run on other systems.
+	To install Fox-Toolkit manually, download the source package from
+	http://www.fox-toolkit.org, extract it, and run the following from
+	within the extracted source:
+		./configure && make && make install
+
+	Windows:
+	---------
+	On Windows, if you want to build the test GUI, you will need to get
+	the hidapi-externals.zip package from the download site.  This
+	contains pre-built binaries for Fox-toolkit.  Extract
+	hidapi-externals.zip just outside of hidapi, so that
+	hidapi-externals and hidapi are on the same level, as shown:
+
+	     Parent_Folder
+	       |
+	       +hidapi
+	       +hidapi-externals
+
+	Again, this step is not required if you do not wish to build the
+	test GUI.
+
+
+Building HIDAPI into a shared library on Unix Platforms:
+---------------------------------------------------------
+
+On Unix-like systems such as Linux, FreeBSD, Mac, and even Windows, using
+Mingw or Cygwin, the easiest way to build a standard system-installed shared
+library is to use the GNU Autotools build system.  If you checked out the
+source from the git repository, run the following:
+
+	./bootstrap
+	./configure
+	make
+	make install     <----- as root, or using sudo
+
+If you downloaded a source package (ie: if you did not run git clone), you
+can skip the ./bootstrap step.
+
+./configure can take several arguments which control the build. The two most
+likely to be used are:
+	--enable-testgui
+		Enable build of the Test GUI. This requires Fox toolkit to
+		be installed.  Instructions for installing Fox-Toolkit on
+		each platform are in the Prerequisites section above.
+
+	--prefix=/usr
+		Specify where you want the output headers and libraries to
+		be installed. The example above will put the headers in
+		/usr/include and the binaries in /usr/lib. The default is to
+		install into /usr/local which is fine on most systems.
+
+Building the manual way on Unix platforms:
+-------------------------------------------
+
+Manual Makefiles are provided mostly to give the user and idea what it takes
+to build a program which embeds HIDAPI directly inside of it. These should
+really be used as examples only. If you want to build a system-wide shared
+library, use the Autotools method described above.
+
+	To build HIDAPI using the manual makefiles, change to the directory
+	of your platform and run make. For example, on Linux run:
+		cd linux/
+		make -f Makefile-manual
+
+	To build the Test GUI using the manual makefiles:
+		cd testgui/
+		make -f Makefile-manual
+
+Building on Windows:
+---------------------
+
+To build the HIDAPI DLL on Windows using Visual Studio, build the .sln file
+in the windows/ directory.
+
+To build the Test GUI on windows using Visual Studio, build the .sln file in
+the testgui/ directory.
+
+To build HIDAPI using MinGW or Cygwin using Autotools, use the instructions
+in the section titled "Building HIDAPI into a shared library on Unix
+Platforms" above.  Note that building the Test GUI with MinGW or Cygwin will
+require the Windows procedure in the Prerequisites section above (ie:
+hidapi-externals.zip).
+
+To build HIDAPI using MinGW using the Manual Makefiles, see the section
+"Building the manual way on Unix platforms" above.
+
+HIDAPI can also be built using the Windows DDK (now also called the Windows
+Driver Kit or WDK). This method was originally required for the HIDAPI build
+but not anymore. However, some users still prefer this method. It is not as
+well supported anymore but should still work. Patches are welcome if it does
+not. To build using the DDK:
+
+   1. Install the Windows Driver Kit (WDK) from Microsoft.
+   2. From the Start menu, in the Windows Driver Kits folder, select Build
+      Environments, then your operating system, then the x86 Free Build
+      Environment (or one that is appropriate for your system).
+   3. From the console, change directory to the windows/ddk_build/ directory,
+      which is part of the HIDAPI distribution.
+   4. Type build.
+   5. You can find the output files (DLL and LIB) in a subdirectory created
+      by the build system which is appropriate for your environment. On
+      Windows XP, this directory is objfre_wxp_x86/i386.
+
+Cross Compiling
+================
+
+This section talks about cross compiling HIDAPI for Linux using autotools.
+This is useful for using HIDAPI on embedded Linux targets.  These
+instructions assume the most raw kind of embedded Linux build, where all
+prerequisites will need to be built first.  This process will of course vary
+based on your embedded Linux build system if you are using one, such as
+OpenEmbedded or Buildroot.
+
+For the purpose of this section, it will be assumed that the following
+environment variables are exported.
+
+	$ export STAGING=$HOME/out
+	$ export HOST=arm-linux
+
+STAGING and HOST can be modified to suit your setup.
+
+Prerequisites
+--------------
+
+Note that the build of libudev is the very basic configuration.
+
+Build Libusb. From the libusb source directory, run:
+	./configure --host=$HOST --prefix=$STAGING
+	make
+	make install
+
+Build libudev. From the libudev source directory, run:
+	./configure --disable-gudev --disable-introspection --disable-hwdb \
+		 --host=$HOST --prefix=$STAGING
+	make
+	make install
+
+Building HIDAPI
+----------------
+
+Build HIDAPI:
+
+	PKG_CONFIG_DIR= \
+	PKG_CONFIG_LIBDIR=$STAGING/lib/pkgconfig:$STAGING/share/pkgconfig \
+	PKG_CONFIG_SYSROOT_DIR=$STAGING \
+	./configure --host=$HOST --prefix=$STAGING

+
+There are two implementations of HIDAPI for Linux. One (linux/hid.c) uses the
+Linux hidraw driver, and the other (libusb/hid.c) uses libusb. Which one you
+use depends on your application. Complete functionality of the hidraw
+version depends on patches to the Linux kernel which are not currently in
+the mainline. These patches have to do with sending and receiving feature
+reports. The libusb implementation uses libusb to talk directly to the
+device, bypassing any Linux HID driver. The disadvantage of the libusb
+version is that it will only work with USB devices, while the hidraw
+implementation will work with Bluetooth devices as well.
+
+To use HIDAPI, simply drop either linux/hid.c or libusb/hid.c into your
+application and build using the build parameters in the Makefile.
+
+
+Libusb Implementation notes
+----------------------------
+For the libusb implementation, libusb-1.0 must be installed. Libusb 1.0 is
+different than the legacy libusb 0.1 which is installed on many systems. To
+install libusb-1.0 on Ubuntu and other Debian-based systems, run:
+	sudo apt-get install libusb-1.0-0-dev
+
+
+Hidraw Implementation notes
+----------------------------
+For the hidraw implementation, libudev headers and libraries are required to
+build hidapi programs.  To install libudev libraries on Ubuntu,
+and other Debian-based systems, run:
+	sudo apt-get install libudev-dev
+
+On Redhat-based systems, run the following as root:
+	yum install libudev-devel
+
+Unfortunately, the hidraw driver, which the linux version of hidapi is based
+on, contains bugs in kernel versions < 2.6.36, which the client application
+should be aware of.
+
+Bugs (hidraw implementation only):
+-----------------------------------
+On Kernel versions < 2.6.34, if your device uses numbered reports, an extra
+byte will be returned at the beginning of all reports returned from read()
+for hidraw devices. This is worked around in the libary. No action should be
+necessary in the client library.
+
+On Kernel versions < 2.6.35, reports will only be sent using a Set_Report
+transfer on the CONTROL endpoint. No data will ever be sent on an Interrupt
+Out endpoint if one exists. This is fixed in 2.6.35. In 2.6.35, OUTPUT
+reports will be sent to the device on the first INTERRUPT OUT endpoint if it
+exists; If it does not exist, OUTPUT reports will be sent on the CONTROL
+endpoint.
+
+On Kernel versions < 2.6.36, add an extra byte containing the report number
+to sent reports if numbered reports are used, and the device does not
+contain an INTERRPUT OUT endpoint for OUTPUT transfers.  For example, if
+your device uses numbered reports and wants to send {0x2 0xff 0xff 0xff} to
+the device (0x2 is the report number), you must send {0x2 0x2 0xff 0xff
+0xff}. If your device has the optional Interrupt OUT endpoint, this does not
+apply (but really on 2.6.35 only, because 2.6.34 won't use the interrupt
+out endpoint).

+# SYNOPSIS
+#
+#   AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   This macro figures out how to build C programs using POSIX threads. It
+#   sets the PTHREAD_LIBS output variable to the threads library and linker
+#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+#   flags that are needed. (The user can also force certain compiler
+#   flags/libs to be tested by setting these environment variables.)
+#
+#   Also sets PTHREAD_CC to any special C compiler that is needed for
+#   multi-threaded programs (defaults to the value of CC otherwise). (This
+#   is necessary on AIX to use the special cc_r compiler alias.)
+#
+#   NOTE: You are assumed to not only compile your program with these flags,
+#   but also link it with them as well. e.g. you should link with
+#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+#   If you are only building threads programs, you may wish to use these
+#   variables in your default LIBS, CFLAGS, and CC:
+#
+#     LIBS="$PTHREAD_LIBS $LIBS"
+#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+#     CC="$PTHREAD_CC"
+#
+#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+#   has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
+#   (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+#   Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
+#   PTHREAD_PRIO_INHERIT symbol is defined when compiling with
+#   PTHREAD_CFLAGS.
+#
+#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
+#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+#   is not found. If ACTION-IF-FOUND is not specified, the default action
+#   will define HAVE_PTHREAD.
+#
+#   Please let the authors know if this macro fails on any platform, or if
+#   you have any other suggestions or comments. This macro was based on work
+#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
+#   grateful for the helpful feedback of numerous users.

+# This is a sample udev file for HIDAPI devices which changes the permissions

+
+
+# If you are using the libusb implementation of hidapi (libusb/hid.c), then
+# use something like the following line, substituting the VID and PID with
+# those of your device. Note that for kernels before 2.6.24, you will need
+# to substitute "usb" with "usb_device". It shouldn't hurt to use two lines
+# (one each way) for compatibility with older systems.
+
+# HIDAPI/libusb
+SUBSYSTEM=="usb", ATTRS{idVendor}=="04d8", ATTRS{idProduct}=="003f", MODE="0666"

+
+# If you are using the hidraw implementation (linux/hid.c), then do something
+# like the following, substituting the VID and PID with your device. Busnum 1
+# is USB.
+
+# HIDAPI/hidraw
+KERNEL=="hidraw*", ATTRS{busnum}=="1", ATTRS{idVendor}=="04d8", ATTRS{idProduct}=="003f", MODE="0666"
+
+# Once done, optionally rename this file for your device, and drop it into
+# /etc/udev/rules.d and unplug and re-plug your device. This is all that is
+# necessary to see the new permissions. Udev does not have to be restarted.
+
+# Note that the hexadecimal values for VID and PID are case sensitive and
+# must be lower case.
+
+# If you think permissions of 0666 are too loose, then see:
+# http://reactivated.net/writing_udev_rules.html for more information on finer
+# grained permission setting. For example, it might be sufficient to just
+# set the group or user owner for specific devices (for example the plugdev
+# group on some systems).
