* DESCRIPTION:
* port selection page of WIA class installer.
*
* 1. Create CDevice object of selected device.
* 2. Process INF of selected device thru CDevice.
* 3. Get all Port's CreatFile name and Friendly name, store locally.
* 4. Handle Port selection UI and set CreateFile name thru CDevice.
* 5. Delele CDevice object if user re-select another device.
