* @brief This file provides the HID core functions.
*
* @verbatim
*
* ===================================================================
* HID Class Description
* ===================================================================
* This module manages the HID class V1.11 following the "Device Class Definition
* for Human Interface Devices (HID) Version 1.11 Jun 27, 2001".
* This driver implements the following aspects of the specification:
* - The Boot Interface Subclass
* - The Mouse protocol
* - Usage Page : Generic Desktop
* - Usage : Joystick
* - Collection : Application
*
* @note In HS mode and when the DMA is used, all variables and data structures
* dealing with the DMA during the transaction process should be 32-bit aligned.
*
