This example implements a USB MIDI device to demonstrate the use of the
USB device stack. It implements the device configuration found in Appendix
B of the Universal Serial Bus Device Class Definition for MIDI Devices.
The 'USER' button sends note on/note off messages.
The board will also react to identity request (or any other data sent to
the board) by transmitting an identity message in reply.
