+ * CUSTOM_HID Class Description
+ * ===================================================================
+ * This module manages the CUSTOM_HID class V1.11 following the "Device Class Definition
+ * for Human Interface Devices (CUSTOM_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.
