On a new G4/400, there are 2 USB ports. The keyboard goes in one, and the iMate has to go in the other (it does not work when plugged into the extra USB port on the keyboard). So where do I connect the ATM8? Can I use the USB port on the keyboard? I hope I don't have to buy a hub now, after having bought the iMate. The hated dongle is becoming very expensive indeed. Thanks in advance for any advice. Tony Maxwell
