+  * @author  MCD Application Team
+  * @brief   This file provides the high layer firmware functions to manage the
+  *          following functionalities of the USB CDC Class:
+  *           - Initialization and Configuration of high and low layer
+  *           - Enumeration as CDC Device (and enumeration for each implemented memory interface)
+  *           - OUT/IN data transfer
+  *           - Command IN transfer (class requests management)
+  *           - Error management
+  *
+  *  @verbatim

+  *          ===================================================================
+  *                                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
+  *
+  *           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):
+  *             - Any class-specific aspect relative to communication classes should be managed by user application.
+  *             - All communication classes other than PSTN are not managed
