******************************************************************************
* @file stm32f1xx_hal_hcd.c
* @author MCD Application Team
* @version V1.1.1
* @date 12-May-2017
* @brief HCD HAL module driver.
* This file provides firmware functions to manage the following
* functionalities of the USB Peripheral Controller:
* + Initialization and de-initialization functions
* + IO operation functions
* + Peripheral Control functions
* + Peripheral State functions
*
@verbatim
==============================================================================
##### 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();
