DeviceType
Set when a driver calls IoCreateDevice as appropriate for the type of underlying device. A driver writer can define a new FILE_DEVICE_XXX with a value in the customer range 32768 to 65535 if none of the system-defined values describes the type of a new device. For a list of the system-defined values, see the FILE_DEVICE_XXX in Chapter 1 of Part II in this manual.
Characteristics
