 * \brief Management of the USB device controller.
 *
 * The USB task checks the income of new requests from the USB host.
 * When a setup request occurs, this task launches the processing of this
 * setup contained in the usb_standard_request.c file.
 * Other class-specific requests are also processed in this file.
 *
 * - Compiler:           IAR EWAVR32 and GNU GCC for AVR32
 * - Supported devices:  All AVR32 devices with a USB module can be used.
