I have a Win XP Pro desktop box that has a DVD burners in it. It was working. Had some problems so I swapped it out with a newer one (ASUS DRW-24B1ST in one machine). XP reports that it successfully loaded the device driver for this hardware but cannot find the hardware device (Code 41).
The BIOS sees it fine.
Same thing is happening with a HP Scanjet scanner that is plugged into a USB port. It isn't seeing any USB device any longer.
Not even sure where to start on this one.
