  *  Keyboard host demonstration application. This gives a simple reference
  *  application for implementing a USB keyboard, for USB keyboards using
  *  the standard keyboard HID profile.

  *  This uses a naive method where the keyboard is set to Boot Protocol mode, so
  *  that the report structure is fixed and known. A better implementation
  *  uses the HID report parser for correct report data processing across
  *  all compatible mice with advanced characteristics, as shown in the
  *  KeyboardHostWithParser demo application.
