- * @file stm32f1xx_ll_usb.c
- * @author MCD Application Team
- * @brief USB Low Layer HAL module driver.
- *
- * 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
- *
- @verbatim
- ==============================================================================
- ##### 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.
