I have an HP Pavilion laptop with 2 USB 1 ports. I also have an external DVD drive, an external hard drive as well as several USB accessories (wireless mouse, thumb drive, etc). All the above are USB 2, but backwards-compatible to work with USB 1.
Everything was fine until recently the computer stopped recognizing the DVD drive and the external hard drive. When I plug either in I get the usual “this device could work faster in a USB 2 port” pop up balloon. But when I look in My Computer the drives are not listed. When I try to run a DVD burning program, the DVD drive is not listed in the menu of drive choices.
The thumb drive and the wireless mouse run fine through these same USB ports.
When I check Device Manager, I’ve got the yellow exclamation point over USB Mass Storage Device, and under properties it shows “error 10”. I did the recommended troubleshoot-delete the device, plug it in, run Add New Hardware wizard. It finds the device, then says there was an error installing it and it may not work properly. Then I’m back to square one, the devices not found in My Computer.
The same thing happens on my desktop computer, which also has USB 1 ports.
Both computers are running XP Pro with service pack 2 and all the latest updates. Both the DVD drive and the external hard drive work fine other peoples computers.
Neither the DVD drive (Mad Dog Multimedia) nor the hard drive (Western Digital) have any driver updates available.
I have a feeling this is a Windows compatibility problem, not a physical USB port problem, but I’m at a loss. Any suggestions?
