[32]Unknown device

Since I have Vista up and running without any major issue. I want to take care of some annoyances. I have a "unknown device" in device manager and for the life of me I can't figure out what it is for. It claims to be on a pci bus, but I have drivers installed for all my pci devices. Also is there any know bugs with Vista for a restart issue? Sometimes when I restart it will log off windows. Seems to restart except it goes to a black screen and hangs. Have to restart manually then. This doesn't happen all the time.

Have you downloaded and installed the drivers for the motherboard itself?

Are you using a Creative sound card with a game port? I know that Vista has some issues with gameports and they'll show up as Unknowns.
As for the restart, I know that older versions of Norton AV will cause similar problems. You may have a startup program that's hanging you up. Does the black screen occur before or after the MS progress bar?

I have the same problem, as I am still running on beta chipset drivers. We can try and identify exactly what it is, in DM, right-click on the device and choose Properties, then in the Details tab select "Hardware IDs" from the drop-down list. Post back what it reports.

I don't think the restart issue has anything to do with hanging program. Windows logs off and closes just fine. Its at the end of the reboot where you computer usually cuts the monitor off for a sec then goes on to post. Basically like this. Start>Restart>Windows Logs Off>Black Screen. I'm using Vista's default mobo drivers. I have a Soyo KT600. And I can't to seem to find anything on there site remotely dealing with Vista drivers for any product.. I'm currently using on board sound, so no go on the creative game port. The hardware ID is

ACPI\PNPB006
*PNPB006

There may be a partial/temporary solution offered here

The final Yellow flag was harder to trackdown, and may be the one identified by gehanna. When you look at it's properties, it has a Hardware ID of ACPI/PNPB006. It turns out that it is the NVIDIA(R) nForce(TM) MIDI UART. Whilst I believe that one option is to turn this off in the BIOS, I hate admitting defeat like this. I was actually able to install the driver from the old Windows XP 6.86 nForce AMD package I had on the HDD where I keep all of my old drivers. I pointed the Install Driver dialogue at the AudioDrv subdirectory of the previously used driver package here. (i'm sure that NVIDIA will update this part of their Vista Driver soon. They seem to be working on a lot right now!

If that's an Asus motherboard, then what it is is either the onboard MIDI controller or the onboard Game port. Asus have decided not to support them in Vista, but you can go into the BIOS Setup and disable them and the yellow splat will disappear from DM.

Not a Asus motherboard, but I guess it affects Soyo motherboards to. Disable midi and gameport and its gone. One problem down. Any clues on the restart issue?

Hello jayclark :)

Try this
Start Button and type performance into the search box
From the results select “Performance Information and tools”
Click “Generate a system health report”
Under “Basic system checks” expand all the categories to see if any problems reported

I think I read once of video drivers causing this problem

Nothing came up on the report. But pointing towards the video drivers was dead on I think. Uninstalled the umm not so good Nvidia drivers to say it nicely and used Vista's wddm drivers and the hang seems to have gone away, and there is no performance lost either since the Nvidia drivers didn't add any performance what so ever.

Great :)

The black screen is about the only problem I have not had with Nvidia drivers.
I`m still waiting for a good one.:(
