                    ##### How to use this driver #####
  ==============================================================================
  [..]
    (#)Declare a HCD_HandleTypeDef handle structure, for example:
       HCD_HandleTypeDef  hhcd;
        
    (#)Fill parameters of Init structure in HCD handle
  
    (#)Call HAL_HCD_Init() API to initialize the HCD peripheral (Core, Host core, ...) 

    (#)Initialize the HCD low level resources through the HAL_HCD_MspInit() API:
        (##) Enable the HCD/USB Low Level interface clock using the following macro
             (+++) __HAL_RCC_USB_OTG_FS_CLK_ENABLE()
           
        (##) Initialize the related GPIO clocks
        (##) Configure HCD pin-out
        (##) Configure HCD NVIC interrupt
    
    (#)Associate the Upper USB Host stack to the HAL HCD Driver:
        (##) hhcd.pData = phost;

    (#)Enable HCD transmission and reception:
        (##) HAL_HCD_Start();
