     * to identify devices.

     * must not change when system is running and the device exists.
     *   3. The ID of logical device must be NOT reusable. If a device is
     * removed, other newly created logical device must not use the same ID.
     *   4. The ID must not be zero or 0xFFFFFFFF.
