* \brief LUFA Custom Board LED Hardware Driver (Template)
*
* 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 LEDs driver,
* for the LEDs (up to four) mounted on most development boards.
