+ ******************************************************************************
+ * @file usbd_cdc.c
+ * @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
+ *
