+  * @brief   CMSIS Cortex-M4 Device Peripheral Access Layer System Source File.
+  *
+  * 1. This file provides two functions and one global variable to be called from
+  *    user application:
+  *      - SystemInit(): This function is called at startup just after reset and 
+  *                      before branch to main program. This call is made inside
+  *                      the "startup_stm32f3xx.s" file.
+  *
+  *      - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
+  *                                  by the user application to setup the SysTick
+  *                                  timer or configure other parameters.
+  *
+  *      - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
+  *                                 be called whenever the core clock is changed
+  *                                 during program execution.
+  *
+  * 2. After each device reset the HSI (8 MHz) is used as system clock source.
+  *    Then SystemInit() function is called, in "startup_stm32f3xx.s" file, to
+  *    configure the system clock before to branch to main program.
+  *
+  * 3. This file configures the system clock as follows:

+  *
+  * 1. This file provides two functions and one global variable to be called from
+  *    user application:
+  *      - SystemInit(): This function is called at startup just after reset and 
+  *                      before branch to main program. This call is made inside
+  *                      the "startup_stm32f3xx.s" file.
+  *
+  *      - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
+  *                                  by the user application to setup the SysTick
+  *                                  timer or configure other parameters.
+  *
+  *      - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
+  *                                 be called whenever the core clock is changed
+  *                                 during program execution.
+  *
+  * 2. After each device reset the HSI (8 MHz) is used as system clock source.
+  *    Then SystemInit() function is called, in "startup_stm32f3xx.s" file, to
+  *    configure the system clock before to branch to main program.
+  *
+  * 3. This file configures the system clock as follows:

+  *
+  * @note   - The system frequency computed by this function is not the real

+  *           constant and the selected clock source:

+  *             or HSI_VALUE(*) multiplied/divided by the PLL factors.
+  *
+  *         (*) HSI_VALUE is a constant defined in stm32f3xx_hal.h file (default value
+  *             8 MHz) but the real value may vary depending on the variations
+  *             in voltage and temperature.
+  *
+  *         (**) HSE_VALUE is a constant defined in stm32f3xx_hal.h file (default value
+  *              8 MHz), user has to ensure that HSE_VALUE is same as the real
+  *              frequency of the crystal used. Otherwise, this function may
+  *              have wrong result.

+  * @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
+  *

+  *          ===================================================================
+  *                                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
