Detailed Description

USB Low Layer HAL module driver.

Author:
MCD Application Team
Version:
V1.1.0
Date:
16-September-2015 This file provides firmware functions to manage the following functionalities of the USB Peripheral Controller: + Initialization/de-initialization functions + I/O operation functions + Peripheral Control functions + Peripheral State functions
  ==============================================================================
                    ##### How to use this driver #####
  ==============================================================================
    [..]
      (#) 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.
