+ * @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

+ ##### 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 macros
+ (+++) __HAL_RCC_USB_OTG_FS_CLK_ENABLE();
+ (+++) __HAL_RCC_USB_OTG_HS_CLK_ENABLE(); (For High Speed Mode)
+ (+++) __HAL_RCC_USB_OTG_HS_ULPI_CLK_ENABLE(); (For High Speed Mode)
+
+ (##) 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();
