Introduction

The gousb package is an attempt at wrapping the libusb library into a Go-like binding.

Supported platforms include:

  • linux
  • darwin
  • windows

Installation on Linux

Dependencies

You must first install libusb-1.0. This is pretty straightforward on linux and darwin. The cgo package should be able to find it if you install it in the default manner or use your distribution's package manager. How to tell cgo how to find one installed in a non-default place is beyond the scope of this README.

Note: If you are installing this on darwin, you will probably need to run fixlibusb_darwin.sh /usr/local/lib/libusb-1.0/libusb.h because of an LLVM incompatibility. It shouldn't break C programs, though I haven't tried it in anger.

Example: lsusb

The gousb project provides a simple but useful example: lsusb. This binary will list the USB devices connected to your system and various interesting tidbits about them, their configurations, endpoints, etc. To install it, run the following command:

go get -v github.com/thorduri/go-libusb/lsusb

gousb

If you installed the lsusb example, both libraries below are already installed.

Installing the primary gousb package is really easy:

go get -v github.com/thorduri/go-libusb/usb

There is also a usbid package that will not be installed by default by this command, but which provides useful information including the human-readable vendor and product codes for detected hardware. It's not installed by default and not linked into the usb package by default because it adds ~400kb to the resulting binary. If you want both, they can be installed thus:

go get -v github.com/thorduri/go-libusb/usb{,id}

Documentation

The documentation can be viewed via local godoc or via the excellent godoc.org:
