-**This package is discontinued**
-This package does not work with Go1.6+. I won't be updating this package since a better alternative is already available, please take a look at [karalabe/hid](https://github.com/karalabe/hid).
-
-
-## go.hid
-This [go](http://golang.org) package wraps the [signal11/hidapi](https://github.com/signal11/hidapi) and provides communication with USB Human Interface Devices.
-
-**This package is not completely tested yet!**
-
-### Installation:
-This project depends on libhidapi, which must be installed manually.
-```shell
-git clone git@github.com:signal11/hidapi.git
-cd hidapi
-./bootstrap
-./configure
-```
-
-Now change directory depending on your OS.
-
-For linux + hidraw: `cd linux`. (requires libudev. Package libudev-dev on debian/ubuntu.)
-
-For linux + libusb: `cd libusb`. (requires libusb. Package libusb-1.0-0-dev on debian/ubuntu.)
-
-For mac: `cd mac`.
-
-For windows: `cd windows`.
-
-Make and install.
-For linux/mac:
-```
-make
-sudo make install
-```
-For windows:
-```
-run some wizzard, probably.. (PR on readme is very welcome)
-```
-
-Lastly, for linux only:
-Create a symlink pointing libhidapi.so to the version you chose:
-
-For linux + hidraw: `cd /usr/local/lib; sudo ln -s libhidapi-hidraw.so libhidapi.so`
-
-For linux + libusb: `cd /usr/local/lib; sudo ln -s libhidapi-libusb.so libhidapi.so`
-
-For more instructions on libhidapi, please visit [signal11/hidapi](https://github.com/signal11/hidapi).
-
-When you have installed hidapi lib, install this package with `go get github.com/GeertJohan/go.hid`.
-
-### Documentation:
-[godoc.org/github.com/GeertJohan/go.hid](https://godoc.org/github.com/GeertJohan/go.hid)
-
-### Example:
-This is a simple example on how to use feature reports. For a working example view [GeertJohan/mgl](https://github.com/GeertJohan/mgl).
-```go
-package main
-
-import(
- "log"
- "github.com/GeertJohan/go.hid"
-)
-
-func main() {
- // open the MSI GT leds device
- leds, err := hid.Open(0x1770, 0xff00, "")
- if err != nil {
- log.Fatalf("Could not open leds device: %s", err)
- }
- defer leds.Close()
-
- // create a feature report. This is always 8*n+1 bytes long, where n is >1.
- data := make([]byte, 9)
- data[0] = 0x42 // report ID
- data[1] = 0x00 // dummy data
- data[2] = 0x01 // dummy data
- data[3] = 0x02 // dummy data
- data[4] = 0x03 // dummy data
- data[5] = 0x04 // dummy data
- data[6] = 0x05 // dummy data
- data[7] = 0x06 // dummy data
- data[8] = 0x07 // dummy data
-
- _, err := leds.SendFeatureReport(data)
- if err != nil {
- log.Fatalf("Could not send feature report to do dummy action. %s\n", err)
- }
-}
-```

-### License:
-The go code in this project is licenced under a a Simplified BSD license. Please read the [LICENSE file](LICENSE).
-
-### TODO:
-At this point, the package works for linux with hidraw.
-hidapi itself is already cross-platform, so making this package work cross-platform shouldn't be a lot of work.
-- Make this package work cross-platform.
-- Add better support for hidapi init() and exit(). (At this time hidapi's init() is called once on first Open() call)
-- Add tests (find if there is a usb-hid dummy device that has expected input/output and works consistently within an OS (we can write a test file for each OS seperated))
-- Better example (preferably with a dummy test device)
-
-### History:
-I started this project to be able to communicate with the MSI leds device in the MSI GT780DX laptop. For more information about that project, visit [GeertJohan/mgl](https://github.com/GeertJohan/mgl).
