krebyy 1:3a73d77c2cef 7 * @brief This file provides the high layer firmware functions to manage the
krebyy 1:3a73d77c2cef 8 * following functionalities of the USB CDC Class:
krebyy 1:3a73d77c2cef 9 * - Initialization and Configuration of high and low layer
krebyy 1:3a73d77c2cef 10 * - Enumeration as CDC Device (and enumeration for each implemented memory interface)
krebyy 1:3a73d77c2cef 11 * - OUT/IN data transfer
krebyy 1:3a73d77c2cef 12 * - Command IN transfer (class requests management)
krebyy 1:3a73d77c2cef 13 * - Error management

krebyy 1:3a73d77c2cef 18 * CDC Class Driver Description
krebyy 1:3a73d77c2cef 19 * ===================================================================
krebyy 1:3a73d77c2cef 20 * This driver manages the "Universal Serial Bus Class Definitions for Communications Devices
krebyy 1:3a73d77c2cef 21 * Revision 1.2 November 16, 2007" and the sub-protocol specification of "Universal Serial Bus
krebyy 1:3a73d77c2cef 22 * Communications Class Subclass Specification for PSTN Devices Revision 1.2 February 9, 2007"
krebyy 1:3a73d77c2cef 23 * This driver implements the following aspects of the specification:
krebyy 1:3a73d77c2cef 24 * - Device descriptor management
krebyy 1:3a73d77c2cef 25 * - Configuration descriptor management
krebyy 1:3a73d77c2cef 26 * - Enumeration as CDC device with 2 data endpoints (IN and OUT) and 1 command endpoint (IN)
krebyy 1:3a73d77c2cef 27 * - Requests management (as described in section 6.2 in specification)
krebyy 1:3a73d77c2cef 28 * - Abstract Control Model compliant
krebyy 1:3a73d77c2cef 29 * - Union Functional collection (using 1 IN endpoint for control)
krebyy 1:3a73d77c2cef 30 * - Data interface class
krebyy 1:3a73d77c2cef 31 *
krebyy 1:3a73d77c2cef 32 * These aspects may be enriched or modified for a specific user application.
krebyy 1:3a73d77c2cef 33 *
krebyy 1:3a73d77c2cef 34 * This driver doesn't implement the following aspects of the specification
krebyy 1:3a73d77c2cef 35 * (but it is possible to manage these features with some modifications on this driver):
krebyy 1:3a73d77c2cef 36 * - Any class-specific aspect relative to communication classes should be managed by user application.
krebyy 1:3a73d77c2cef 37 * - All communication classes other than PSTN are not managed
krebyy 1:3a73d77c2cef 38 *
