BleepingComputer.com: Windows XP - UAA Bus Driver needed

Hello,

Within the last two to three weeks everytime I boot up I receive a "Device Found" pop up and then it directs me to install the driver from various locations, which I don't have any way. The driver it is looking for is a UAA Bus Driver for High Definition Audio. I've tried the drivers on my Windows XP disk and drivers from my sound card, but they didn't work. I ran a complete diagnostics check with the disk that came with my computer and it gave me a clean bill of health. I have never had this problem, so I don't know why it started all of a sudden. The are no yellow exclamation marks in the Device Manager and the sound is working great. I've done a lot of reading, but I am too unsure of myself to jump into anything. One suggestion was to go into the Devise Manager and check under System devices. I tried that and I have no System devices in the Device Manager. I checked one of our other computers running Win XP also and it does have the System Devices folder. My computer runs fine, but what would have happened to the System Devices folder & contents? The integrated audio is disabled in the BIOS as I have a Xtreme Sound pci card installed and have for quite some time. I am curious if they are related or not. I have no clue how long there hasn't been a System devices file.

I was given this link, http://support.microsoft.com/kb/835221 , to possibly solve the problem for the UUA bus driver. Microsoft e-mailed the file and info. to me, but the warning they included scared me out of trying it. Especially when everything else is working fine.

It may not be a serious problem, but I would like to take care of it. I would appreciate any help anyone can provide to resolve this issue. At this point I would even appreciate a registry fix to stop the popup when I boot up.

I will check back tomorrow....it's time for bed.

Thank you,
Bill

Hello, welcome to BleepingComputer. The only experience I've had with the Microsoft UAA HD Audio driver was that it worked fine for me when I downgraded my HP laptop supplied with Vista, to XP. As HP only provided Vista driver support for the laptop, I had to locate all the necessary XP drivers.
