+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ The PCD HAL driver can be used as follows:
+
+ (#) Declare a PCD_HandleTypeDef handle structure, for example:
+ PCD_HandleTypeDef hpcd;
+
+ (#) Fill parameters of Init structure in HCD handle
+
+ (#) Call HAL_PCD_Init() API to initialize the PCD peripheral (Core, Device core, ...)
+
+ (#) Initialize the PCD low level resources through the HAL_PCD_MspInit() API:
+ (##) Enable the PCD/USB Low Level interface clock using
+ (+++) __HAL_RCC_USB_OTG_FS_CLK_ENABLE();
+ (+++) __HAL_RCC_USB_OTG_HS_CLK_ENABLE(); (For High Speed Mode)
+
+ (##) Initialize the related GPIO clocks
+ (##) Configure PCD pin-out
+ (##) Configure PCD NVIC interrupt
+
+ (#)Associate the Upper USB device stack to the HAL PCD Driver:
+ (##) hpcd.pData = pdev;
+
+ (#)Enable PCD transmission and reception:
+ (##) HAL_PCD_Start();
+
+ @endverbatim

+ * 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
