-  * @author  MCD Application Team
-  * @version V2.4.2
-  * @date    11-December-2015
-  * @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
