In my experience, it's usually two or 4 ports connected to an internal
hub, where at least one is not on a hub at all. You have to try to find
out which they are. I dont know any similar tool with windows, but
on linux (and i guess *BSD) you can use lsusb to give you a hierarchy
of the USB system on your mainboard. There you can see which ports have
a hub behind them and which dont.
