This protocol can be used on any device handle to obtain generic path/location information concerning the physical device or logical device. If the handle does not logically map to a physical device, the handle may not necessarily support the device path protocol. The device path describes the location of the device the handle is for. The size of the Device Path can be determined from the structures that make up the Device Path.
