Accessing my pc's system devices

Hi, via visual studio C++, I can access COM ports and read in data from the arduino. I can access multiple arduinos this way no problem since they're all named "COMx", where x in a number. But I'd like to be able to access other serial devices, such as my mouse or.. my phone. they're not stored as one of the "COM"s (wait, or are they?), so what are they called?

Try asking the same question in a Microsoft Visual Studio-forum, there is quite a lot more chance that you will get a useful answer.

// Per.

They are HID devices IIRC
