Identifying underlying drivers

[WestfW]

Is there a way to get information about the underlying hardware and/or driver associated with a particular (probably virtual) COM port? COM16: USB Vendor X ID Y SerNo Z
COM22: USB MODEM Vendor X ID Y Serno Z
COM25: TCP driver foo.exe
(or do you have to approach this from the other direction, scanning USB devices (and etc) and figuring out which COM port they provide?)

The devcon example in the WDK shows how to obtain the information you can view in Device Manager and thus might be useful to you:

I found some clues in the USB forums, tracked them down and munged them together and came up with something that seems to more-or-less work.

C:\blah>.\ArduScan

Possible Arduino on COM6, VID 0x0403 PID 0x6001
     Serno FTD61T6QA\0000

Code (cygwin, mingw) here: https://github.com/WestfW/ArduScan
(It's not very pretty, since I'm normally an Embedded C kinda person, rather than a Windows C++ person.)
