* 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.
