 !!!Purpose

    USB Device Driver class definition.

 !!!Usage

    -# Instanciate a USBDDriver object and initialize it using
       USBDDriver_Initialize.
    -# When a USB SETUP request is received, forward it to the standard
       driver using USBDDriver_RequestHandler.
    -# Check the Remote Wakeup setting via USBDDriver_IsRemoteWakeUpEnabled.
