- * ===================================================================
- * 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.
