I have a G4 Cube with the standard USB speakers and I've read now that the iSub should work with it now. But I'm riddled about the connections. I don't have an ADC monitor so I have only 2 USB ports, one for my keyboard and one for my standard speakers. Does anyone know if you can connect the iSub to your keyboard hub or a standard hub without having interference of the sound signal? Or does there exist an adapter which you plug into your ADC port and get an extra USB port? So if anyone knows something about this, I'd appreciate your thoughts.
