I just bought a Logitech Rumblepad 2 cordless to use with my Mini Media center and NES and SNES emulators. It works fantastic! Now we want another controller for 2 player and I realize I am out of USB ports on my Mini (its an old G4 Mini). Aside from buying a USB hub I thought that I might be able to use only one of the USB sensors for two of these controllers. I was searching the Google and didn't come up with much. Anyone have any input on this idea?
