+The USB-FS-Device Audio Speaker demo gives examples of how to use the STM32F10xxx 
+and STM32L15xxx USB-FS-Device peripheral to communicate with the PC host in the 
+isochronous transfer mode.
+It provides a demonstration of the correct method for configuring an isochronous
+endpoint, receiving or transmitting data from/to the host.
+
+More details about this Demo implementation is given in the User manual 
+"UM0424 STM32F10xxx USB development kit", available for download from the ST
+microcontrollers website: www.st.com/stm32

+====================
+This example runs on STMicroelectronics STM3210B-EVAL, STM3210E-EVAL and 
+STM32L152-EVAL evaluation boards and can be easily tailored to any other hardware.
+To select the STMicroelectronics evaluation board used to run the example, uncomment
+the corresponding line in platform_config.h file.
+    
+  - STM3210B-EVAL Set-up 
+     - Jumper JP1 (USB disconnect) should be connected in position 2-3.

+  * @file    system_stm32f10x.c
+  * @author  MCD Application Team
+  * @version V4.0.0
+  * @date    21-January-2013
+  * @brief   CMSIS Cortex-M3 Device Peripheral Access Layer System Source File.
+  * 
+  * 1.  This file provides two functions and one global variable to be called from 
+  *     user application:
+  *      - SystemInit(): Setups the system clock (System clock source, PLL Multiplier
+  *                      factors, AHB/APBx prescalers and Flash settings). 
+  *                      This function is called at startup just after reset and 
+  *                      before branch to main program. This call is made inside
+  *                      the "startup_stm32f10x_xx.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_stm32f10x_xx.s" file, to
+  *    configure the system clock before to branch to main program.
+  *
+  * 3. If the system clock source selected by user fails to startup, the SystemInit()
+  *    function will do nothing and HSI still used as system clock source. User can 
+  *    add some code to deal with this issue inside the SetSysClock() function.
+  *
+  * 4. The default value of HSE crystal is set to 8 MHz (or 25 MHz, depedning on
+  *    the product used), refer to "HSE_VALUE" define in "stm32f10x.h" file. 
+  *    When HSE is used as system clock source, directly or through PLL, and you
+  *    are using different crystal you have to adapt the HSE value to your own
+  *    configuration.
+  *

+        - For Connectivity line devices an external 25MHz crystal is used to drive

+  * @file    system_stm32l1xx.c
+  * @author  MCD Application Team
+  * @version V4.0.0
+  * @date    21-January-2013
+  * @brief   CMSIS Cortex-M3 Device Peripheral Access Layer System Source File.
+  *          This file contains the system clock configuration for STM32L1xx Ultra
+  *          Low Power devices, and is generated by the clock configuration
+  *          tool "STM32L1xx_Clock_Configuration_V1.1.0.xls".
+  *             
+  * 1.  This file provides two functions and one global variable to be called from 
+  *     user application:
+  *      - SystemInit(): Setups the system clock (System clock source, PLL Multiplier
+  *                      and Divider factors, AHB/APBx prescalers and Flash settings),
+  *                      depending on the configuration made in the clock xls tool. 
+  *                      This function is called at startup just after reset and 
+  *                      before branch to main program. This call is made inside
+  *                      the "startup_stm32l1xx_xx.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 MSI (2.1 MHz Range) is used as system clock source.
+  *    Then SystemInit() function is called, in "startup_stm32l1xx_xx.s" file, to
+  *    configure the system clock before to branch to main program.    
+  *    
+  * 3. If the system clock source selected by user fails to startup, the SystemInit()
+  *    function will do nothing and MSI still used as system clock source. User can 
+  *    add some code to deal with this issue inside the SetSysClock() function.
+  * 
+  * 4. The default value of HSE crystal is set to 8MHz, refer to "HSE_VALUE" define
+  *    in "stm32l1xx.h" file. When HSE is used as system clock source, directly or
+  *    through PLL, and you are using different crystal you have to adapt the HSE
+  *    value to your own configuration.
+  * 
+  * 5. This file configures the system clock as follows:
