00032  * \section Purpose
00033  *
00034  *    Definition of several callbacks which are triggered by the USB software
00035  *    driver after receiving specific requests.
00036  *
00037  * \section Usage
00038  *
00039  *    -# Re-implement the USBDDriverCallbacks_ConfigurationChanged
00040  *        callback to know when the hosts changes the active configuration of
00041  *        the device.
00042  *    -# Re-implement the USBDDriverCallbacks_InterfaceSettingChanged
00043  *        callback to get notified whenever the active setting of an interface
00044  *        is changed by the host.
00045  *
00046  * \addtogroup usbd_interface
