// Device Name - this string is the name of the device. It is the name
// that when added to the name of the root of the device tree and with
// the device number appended, gives the name of the device required for
// a call to NtOpenFile.
// So for example, if the root is \Device and the Device type is
// MMAux and the device number is 2, the full name is \Device\MMAux2
