If you go to device manager and expand the problem device then right
click/properties. Select the Details tab. Make a note of the Device
Instance ID. The VEN_xxxx & DEV_xxxx codes will be a source of
locating the offending driver using Google.

Search for the string VEN_xxx&DEV_xxxx and you should get links to
the manufacturer. From there it requires a little thought as to the
type of device but it may be obvious when the search results come back.

Example:

Device in Device manager....

VEN_10EC&DEV_0888 (in this case a Realtek High Definition Audio device)
