The question still lingers in my mind why Sony DVD drive says the very first thing on their FAQ/Troubleshooting, "if using XP update USB 2.0 driver" There must be something they found during testing. Or maybe it is what you said, some bios setting.

>Hmmm, I wonder if there might be some BIOS setting that interacts with "auto-detect" or plug-and-play? Just a wild stab in the dark here.

>>Good point and I thought about it. I plugged a Pocket PC into this new USB but with the same result, even worse, the coputer does not even recognize that something is in the USB port. At least with the DVD it says Device not recognized. By the way, in the DVD drive manual FAQ it says, for XP OS, "update your USB 2.0 driver." But I just can't find on the MSFT site the link to update this driver.

>>Thank you for your suggestion.

>>>Have you tried any other USB device in one of the new port?
>>>
>>>Just thinking that it might be your DVD device that has the problem.
>>>Did the DVD come with some driver that needs installation?
