This Document describes the USB Physical Interface Device or PID Class. The PID Class is intended as an extension of the Human Interface Device (HID) Class for devices that require “real-time” physical feedback. The main focus for the definition is for the use of haptic devices and the implementation of force feedback systems. However there is no requirement that members of this class generate this type of effect. Examples of devices that are member of this class are force feedback joysticks, motion platforms,and force feedback exoskeletons.
1.2 Purpose
This document is intended to supplement to the USB specification and provide manufacturers of PID class devices with the information necessary to build USB compatible devices. Further, this specification specifies how the PID class driver should extract data from USB data streams. Since this device class is an extension of the HID class, the HID class specifications will be required to implement the device functionality.
