   * DEFINITION
   *   Logical device  --- a device that can be accessed by OS.
   *   Physical device --- device attached to the controller.
   *  A logical device can be simply a physical device.
   *
   * Each logical and physical device has a 32bit ID. GUI will use this ID
   * to identify devices.
   *   1. The ID must be unique.
   *   2. The ID must be immutable. Once an ID is assigned to a device, it
   * 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.
