Device Class Definition for HID 1.11

The Device Class Definition for HID 1.11 is intended to supplement the USB Specification and provide HID manufacturers with the information necessary to build USB-compatible devices. It also specifies how the HID class driver should extract data from USB devices. The primary and underlying goals of the HID class definition are to: > be as compact as possible to save device data space > allow the software application to skip unknown information > be extensible and robust > support nesting and collections > be self-describing to allow generic software applications
