* FILE_REV:     1.3
*----------------------------------------------------------------------------
* PURPOSE:
* File defines application-specific configuration of USB driver parameters.
* This firmware uses the standard USB "Communications Device Class" (CDC)
* param's, so that the host PC application software can access the device via
* a "virtual" COM port. (Windows 2000 and XP have built-in USB CDC drivers.)
*
* Atmel's USB-UART 'CDC' library provides functions to emulate UART behaviour,
* so that the application firmware can be made independent of the low-level
* USB protocol.
