Hi,
I have a dell optiplex 7020, with Windows 7 pro 64 bit installed. I have tried to update the system and install all the drivers/application on dell website, but there's still one "Unknown device"
I also tried to uninstall the device driver and let windows to search for any update. But still does not work.
Any idea what this device is? And how to find a driver for it?
Thanks~
