usbhid

A pure Go library to interact with USB HID devices. It can enumerate devices, send and receive every type of HID report.

It works on Linux, Mac and Windows.

Known issues

Blocking API. To interact with it asynchronously please use goroutines/channels and/or some synchronization primitives.

Due to Windows not allowing userspace applications to access the full HID report descriptors, this library can't validate report data sizes on a per-report basis in order to provide the same API for every supported operating system. It can only validate the maximum report size for each report type. Library consumers should know the report descriptors and provide correct data (or validate it themselves). This is the same situation of most mainstream USB HID libraries.

Linux: Several USB HID devices won't be accessible to normal users by default. Depending on the device the user may need to be added to some specific group or to create some udev rule assigning additional permissions. Solving such issues is out of scope of this library.
