*                                CDC Class Driver Description
*          =================================================================== 
*           This driver manages the "Universal Serial Bus Class Definitions for Communications Devices
*           Revision 1.2 November 16, 2007" and the sub-protocol specification of "Universal Serial Bus 
*           Communications Class Subclass Specification for PSTN Devices Revision 1.2 February 9, 2007"
*           This driver implements the following aspects of the specification:
*             - Device descriptor management
*             - Configuration descriptor management
*             - Enumeration as CDC device with 2 data endpoints (IN and OUT) and 1 command endpoint (IN)
*             - Requests management (as described in section 6.2 in specification)
*             - Abstract Control Model compliant
*             - Union Functional collection (using 1 IN endpoint for control)
*             - Data interface class
*
