   This is a stub driver header file, for implementing custom board
   layout hardware with compatible LUFA board specific drivers. If
   the library is configured to use the BOARD_USER board mode, this
   driver file should be completed and copied into the "/Board/" folder
   inside the application's folder.

   This stub is for the board-specific component of the LUFA Joystick
   driver, a small surface mount four-way (plus button) digital joystick
   on most USB AVR boards.
