I am running Windows XP Pro with a HP DVD writer 400i. The CMOS on the intel motherboard sees it. Windows recognizes it when it boots but none of the software sees it. The Windows Device Manager sees it and reports it as working correctly but places the yellow I symbol on it. It has been working fine for several months. I have tried uninstalling the driver and rebooting. Windows finds it a a new device and installs the device driver but still does not work. Any help is appreciated.
