*                                DFU Class Driver Description
*          =================================================================== 
*           This driver manages the DFU class V1.1 following the "Device Class Specification for 
*           Device Firmware Upgrade Version 1.1 Aug 5, 2004".
*           This driver implements the following aspects of the specification:
*             - Device descriptor management
*             - Configuration descriptor management
*             - Enumeration as DFU device (in DFU mode only)
*             - Requests management (supporting ST DFU sub-protocol)
*             - Memory operations management (Download/Upload/Erase/Detach/GetState/GetStatus)
*             - DFU state machine implementation.
*          
*           @note
*            ST DFU sub-protocol is compliant with DFU protocol and use sub-requests to manage
*            memory addressing, commands processing, specific memories operations (ie. Erase) ...
*            As required by the DFU specification, only endpoint 0 is used in this application.
*            Other endpoints and functions may be added to the application (ie. DFU ...)
* 
*           These aspects may be enriched or modified for a specific user application.
*          
*           This driver doesn't implement the following aspects of the specification 
*           (but it is possible to manage these features with some modifications on this driver):
*             - Manifestation Tolerant mode
*      
*
