This minimal USB gamepad driver uses the Usb session to access the USB device and provides Genode's Input service to its client. There is no support for any fancy features like rumble support or, if available, battery state checking. Furthermore there is currently no way to calibrate the analog input sources, which leads to unexpected motion events due to input jitter. For a list of supported devices and more information please look at the README. Fixes #58.
