What's this "Unknown Device" in Device Manager?

I got my X205-SLI4 a few days ago. I uninstalled the Vista Ultimate it came with (along with all the bloatware) and reinstalled a clean version of Viata Ultimate. Then I had to manually find and reinstall all the drivers for the hardware, using either the Driver CD it came with or from Toshiba's website, whichever is the latest one. Well, I think I finished finding and installing all the drivers for the components that show up in Device Manager, EXCEPT for one "Unknown Device". (See attached image). I have no clue what that is, so I downloaded the "Unknown Device Identifier utility and ran it. (See attached image). The utility also found an "Unknown" device and identifies it as belonging to Nvidia Corp. Im suspecting that it's the same one from my Device Manager, and my first thought was that it's a graphics adapter. BUT, I already installed the Nvidia driver for my 8600M GT SLI adapter (it's showing right under the unknown device in the image). So now, Im still lost about this "unknown device". Does anyone know?

 

I believe that might be the bluetooth module that you need the drivers for.

 

Jesse6749, you were dead-on right! I followed your suggestion and installed the "Bluetooth stack" driver and that "unknown" device is now gone. Several new Bluetooth components appear in Device Manager and all seem to be correctly installed. Thanks!

 

Hey guys.
I just installed a fresh copy of Vista Ultimate on my X205-S9359 also. When I
insert the Driver CD that came with my laptop (to get some of the drivers) I see these multiple "QFE" folders. Should I install those drivers also?
Thanks

 

Anyone?
Should I install these "QFE" drivers or are they already included in the Vista SP1?

 

They are probably already included in SP1.
