I believe that's System.IO.Ports.SerialPort.GetPortNames .

Unfortunately, that only covers COM ports, either real or virtual (implemented on USB). It will not find USB ports that do not have virtual COM ports.
I'm digging through some old VB and C++ code to see if I can find some work I did in that regard about 10 years ago.

I haven't been able to locate the USB enumeration code we used, so I can't help you more.
I can tell you that the USB port stuff is contained in the Registry at:
