-  *          This file provides firmware functions to manage the following

-  *           + Initialization/de-initialization functions
-  *           + I/O operation functions
-  *           + Peripheral Control functions
-  *           + Peripheral State functions

-    [..]
-      (#) Fill parameters of Init structure in USB_OTG_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.
