 * \brief
 *      This file contains the USB endpoint 0 management routines corresponding to
 *      the standard enumeration process (refer to chapter 9 of the USB
 *      specification.
 *      This file calls routines of the usb_specific_request.c file for non-standard
 *      request management.
 *      The enumeration parameters (descriptor tables) are contained in the
 *      usb_descriptors.c file.
