I encountered an interesting situation when I updated my mobo's BIOS to version 1405 on my Asus A8N32-SLI Deluxe. The update works fine and installed correctly but when I restarted my computer, Vista had to install drivers. I've updated my BIOS before and was expecting this however, two unknown devices were found. Vista tried installing the drivers but couldn't. After I aborted the driver installation, I was told that the devices were a Yamaha DS-XG Audio Codec and a Creative Webcam Live. This is unusual becuase I've never had these devices. Now that I think about it, I've never bought a Yamaha product and didn't realize they made multimedia components until now. I've also never had a webcam and the only Creative device in my computer is a Soundblaster X-Fi card. I was able to stop Windows from pestering me about missing drivers, but I'm curious as to how this happened.

I dont trust vistas judgment since there is no service pack out. I would try going to the windows update site, and update all drivers for you system.

I did, it was automatic. That's how I learned about the unknown devices.

You have to make sure to go to the WEB SITE for windows updates. Make sure you select CUSTOM updates, rather than express. Gives you more of the hardware updates you might need.

I've been to the windows update website, it just launches the windows update program already in Vista so windowsupdate.com is relatively useless. Besides, why would I be updating hardware I don't have? I did find an update from Silicon Image but that did nothing for the unknown devices. It may just be an issue with the new BIOS.

Usasma posted a link not too long ago for an unknown device detector. I thought I saved it, but I'm having a hard time finding it. I'll keep looking and post back. Maybe he'll chime in with it. Here are a few I found:

I tried the program you suggested. It did not work. After launching the program, it stopped responding. Five minutes later, Windows said the program is no longer responding and I shut it down. Is there a program like this one that runs on Vista x64?

Unknown Devices doesn't like Vista (yes, another one!).

Personally, I don't like drivers from Windows Update - Both Windows Update and HP messed up my system with their video drivers for my HP 750n - it wasn't until I went to nVidia.com that I got a working driver. Since then I recommend getting the driver from the manufacturer of the chipset of the device rather than Windows Update (although I have had some success' with it in Vista).

If the device shows up in Device Manager, try looking at the Details tab of the Properties of that device to see if you can find anything. Google a lot of the unfamiliar terms and you'll start to get an idea of what the device is. Here's a database to help with the search for drivers: http://www.pcidatabase.com/

Finally, I recall hearing that the SoundBlaster has issues with Vista - and this could have caused the misidentification of the device(s). I'd suggest (if available) trying the SoundBlaster drivers for Vista to see if it picks up the questionable devices. Yanking the Creative card and rebooting will tell you if these other devices are associated with the card or not.

I took your advice and Googled the various Hardware IDs. Both ID's go towards some kind of multimedia device, I think I may have issues with the X-Fi card in my computer. I'm planning on getting an Asus Xonar sound card when it's released, that may fix the issue.

Have you checked your bios and made sure the onboard audio is disabled? Sometimes bios updates revert all settings back to default and you have to manually reconfigure it to your preferences.This may be why your getting an unknown device prompt.

Maybe try taking out the card and see if vista pesters you.


When you get the xonar, you can give the x-fi to me! :thumbsup:

I wish Asus would let us know when the card is released. Anyway, shutting off the MIDI and game ports solved the problem.
