I've programmed a couple of embedded devices (based on Rabbit microcontrollers) and TCP/IP over Ethernet is a nice alternative to serial just for simplifying cabling. This path contains the VID and PID of the device amongst other things.

You should not introduce the COM library (ole32.dll) into kernel mode driver (like the CLR does) nor should you use other high level C++ based frameworks like ATL and MFC.
