Unknown Device in Device Manager

Who among us have not seen an unresolved device driver for some device?  You may see after a new install of windows, or notice it on an existing system.  If you are familiar with all the hardware for that computer, you may know exactly what drivers might be required and go searching for it on the vendor site. What if you are not sure.......is there anything you can do?  Of course, there is!  Let's look at an example using Windows 7 installed on a very old IBM Thinkpad T23.



In the example above, the Network Controller has a device issue noted by the ? on Other Devices and the ! on the Network Controller.

Right-click on the unknown Network Controller, and select properties.  Switch to the Details tab.  Change the drop-down Property on that page to Hardware Ids.  I highlighted the Vendor with a value of 1260 and the Device with a value of 3873.





















You can now use the website PCIDatabase.com to help identify the unknown device.



Using the values for Vendor and Device, it shows the unknown device is the wireless LAN card.



If you now click on the vendor, you can search for additional details.





Listed in the notes is a link to the IBM site for the latest drivers.  As it turns out, there was none for this device in order to run either Windows Vista or Windows 7.
