I was recently browsing through Device Manager, and came across the following:
Unfortunately, the properties window didn't provide much insight...
Googling around, I found a useful tip!
If you click "Details", then scroll through the properties, one of the options will have something with "VEN_" in it.
In this case:
VEN (Short for Vendor): 8086
DEV (Short for Device): 29C4
Simply jump along to this site, plug the DEV code in "Device Search", and *Poof* - Component Identified! (In my case, It was the Intel Management Engine Interface. Unfortunately for me, my board is End of Life, so no drivers were made for Windows 7)
For the lazy ones, copy and paste the following, and add the device code to the end :p
Good luck! \o/
