# Gopher Interface Devices (USB HID)
|
|
|
|
The `hid` package is a cross platform library for accessing and communicating with USB Human Interface
|
|
Devices (HID). It is an alternative package to [`gousb`](https://github.com/karalabe/gousb) for use
|
|
cases where devices support this ligher mode of operation (e.g. input devices, hardware crypto wallets).
|
|
|
|
The package wraps [`hidapi`](https://github.com/signal11/hidapi) for accessing OS specific USB HID APIs
|
|
directly instead of using low level USB constructs, which might have permission issues on some platforms.
|
|
On Linux the package also wraps [`libusb`](https://github.com/libusb/libusb). Both of these dependencies
|
|
are vendored directly into the repository and wrapped using CGO, making the `hid` package self-contained
|
|
and go-gettable.
|
|
|
|
Supported platforms at the moment are Linux, macOS and Windows (exclude constraints are also specified
|
|
for Android and iOS to allow smoother vendoring into cross platform projects).
|
|
|
|
## Acknowledgements
|
|
|
|
Although the `hid` package is an implementation from scratch, it was heavily inspired by the existing
|
|
[`go.hid`](https://github.com/GeertJohan/go.hid) library, which seems abandoned since 2015; is incompatible
|
|
with Go 1.6+; and has various external dependencies. Given its inspirational roots, I thought it important
|
|
to give credit to the author of said package too.
|
|
|
|
Wide character support in the `hid` package is done via the [`gowchar`](https://github.com/orofarne/gowchar)
|
|
library, unmaintained since 2013; non buildable with a modern Go release and failing `go vet` checks. As
|
|
such, `gowchar` was also vendored in inline (copyright headers and origins preserved).
