******************************************************************************
* @file usbd_cdc_core.c
* @author MCD Application Team
* @version V1.0.0
* @date 22-July-2011
* @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
* @note
* For the Abstract Control Model, this core allows only transmitting the requests to
* lower layer dispatcher (ie. usbd_cdc_vcp.c/.h) which should manage each request and
* perform relative actions.
*
* 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
*
