    Hello.

    just recently installed win7 x86 and everything seems to be working. I have one remaining unknown device under USB controllers and i am trying to figure out what it belongs to. my webcam works (although i think its listed as usb input device), and parser device, i/o device and texas mem stick have all been installed. i have also noticed that my fingerprint reader says that it is not connected when im first booting into windows although it works properly. could this unknown device have something to do with the reader? any help would be great.

    if everything is working, then don't worry about it... it's a known problem on the new semi-new (last batch of Vista machines) to have 1-2 Unknown devices when installing windows 7 fresh.... The Unknown PCI device is the one that lingers usually, the other unknown device is gotten rid of by using the Firmware Extension Parser driver.

    If it was a vista machine originally, then yes, it's a known problem.
