I've just sorted this problem on another thing I was doing, although I was only up to COM14! It seems there are "hidden" hidden devices. Have a look at this: http://support.microsoft.com/kb/315539 So once you clean out the hidden devices and the hidden, hidden devices, then you can remap your USB Com port back to COM3 or whatever, and it'll stay there! Note that even plugging the same USB-RS232 converter into another USB port on a hub will create a "new" COM port.
