Apologies if I'm teaching people to suck eggs, but having come across this little gem I thought it worth sharing.
If you have a problem with an unknown device in Windows Device manager which cannot update the drivers as a result there is a code displayed which if deciphered will tell you who made it, and what it is.

Highlight the problem device in Device manager right click & select properties. Under the 'events' tab in the bottom window 'Information' a code is displayed, you need the first two parts from it.
\VEN_8086&DEV_2A44
Ven is vendor (8086) Dev is Device (2A44) enter the two codes into PCI Database and it will give you both, in this case 8086 is Intel, and 2A44 is a Chip IC658
It might not immediately solve your problem, but it should narrow the search down enough to make finding drivers or other issues much easier.
