If you want, I can work with you to expand this to include searching for drivers using the Vendor IDs and the Windows Update Catalog site to download and install drivers.
I just went through this trying to install drivers for an unknown device on my system.
Basically, in the Device Manager, I had 2 unknown devices. Windows update was not picking up what these were. I went into the device properties and pulled the Hardware ID values. (They look like PCI\VEN_1180&DEV_0843&SUBSYS_C02F144D&REV_00). I did a web search and found out they were Ricoh codes. My laptop has a 8 in 1 card reader. I then searched the Update Catalog for the device info and was able to install the drivers.
