Unknown PCI device (Device Manager) – How can I find out what drivers I need?

If a PCI device is showing up as an “Unknown Device” in the Windows Device Manager (devmgmt.msc) and you’re not sure what the manufacturer and/or device name is, here’s a quick tip that may help.

Pull up the Properties for the device. Select “Hardware Ids” in the drop-down and make a note of the Vendor (VEN_XXXX) and Device (DEV_XXXX) identifiers (in this example, 8086 and 24C6). With this information you can search for your device at http://www.pcidatabase.com/.


Once you have the vendor and device name, it will increase your chances of finding the correct driver on the manufacturer’s website.
