These unknown devices .. is the HW with a faulty device driver...

you would need to look at the driver file and match it with a device..
... or..
you could just uninstall the unknown device... if the HW is still connected .. it should pop-up as .. New Hardware Found.. which would show you what

PCI Vendor and Device Lists
http://www.pcidatabase.com/index.php

You can look under the Device Details Tab, in the Device properties, and use the "Device Instance ID" to try and identify the MFGR....

Looks like this....
"PCI\VEN_14E4&DEV_1677&SUBSYS_01791028&REV_01\4&1D7EFF9E&0&00E0
"
Use the Vendoir and the Device Search to see if you can get some details....

PCI\VEN_14E4&
DEV_1677&
SUBSYS_01791028&
REV_01\4&1D7EFF9E&0&00E0

uninstalled the unknowns, refreshed, and they just popped back into the unknown category.  It didn't pop up a box asking to install anything.

To identify drivers for your pc do the following:

Start-Programs-Accessories-System Tools-System Information. Click on "components" and highlight "problem devices". Any hardware device with a driver problem will be listed here. Make a note of the first line of the entry. It will contain a Vendor number and a Device number (VEN. . . . DEV. . . .)
both four digits long.
Look up those numbers here:
