 * 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.
