I have a Pacific Digital DVD USB 8x8 which worked great until I purchased and tried out an HP Lightscribe device. My Laptop was running Win XP pro with Acronis 8. With either the Lightscribe or Pacific Digital plugged in, these devices only showed CDROM as the type under my Computer. Properties displayed more info. In the Device manager under CD\DVD the deviices listed were the permanent cd/DVD drive - QSI something and a Lightscribe.

The portable devices could not be written to nor read from. Aconis, Ms Backup, Veritas, Roxio, Nero all could not write to the USB DVD burners. Reported error was media was poor quality.

After trying different solutions, I enter device manager under view selected show all (old items are hidden. First I deleted Acronis referal service device, then I deleted all DVD Rom and CDRom devices except the built in. Then uder USB I removed all old and new USB devuces.

After reinstalling the Pacific Diigital drivers, the device showed up as a DVD/CDROM R+W in the inventory and could be written to with out problems. Then I deinstalled the Pacific Digital including the device listed in the device manager. Installed the Lighscribe drivers and installed the Libhtscribe DVD again everything was good. Lightscribe had no problem writing to the media.

I intend to recreate and document the original problem and then correct the problem recording each step.

The best I can determine is the real devices are picking up old device id's associated with Nero and other software.

Simple thing is, USB is universal. It trys to use universal drivers. It sometimes fails.

Nero is good, and touching computers is how you learn. I learnt the hardway how to uninstall Nero InCD.
