 * \brief     basic functions to setup and enable USB functionality
27
 *
28
 *            usb_common provides the basic functions and interrupt
29
 *            routines to enable USB communication and handling of all
30
 *            basic functions like standard requests, USB reset,
31
 *            descriptor handling etc.\n
32
 *            When a USB Class command or a USB Vendor specific command
33
 *            is received usb_common calls the app_class_cmd or the
34
 *            app_vendor_cmd function. These functions are not implemented
35
 *            here. This is done by the user programm.
