==============================================================================
  [..]
    (#) Fill parameters of Init structure in USB_CfgTypeDef structure.

    (#) Call USB_CoreInit() API to initialize the USB Core peripheral.

    (#) The upper HAL HCD/PCD driver will call the right routines for its internal processes.
