Depends on how the cable busted. If I remember correctly the USB interface was a mouse hack that attached to the spinner. If just the cable is broken away resolder the cable. If the end of the cable is broken (usb connector) then just get a usb cable and cut and attach the new end to the existing cable. If someone has stepped on the mouse board then you will need a new mouse hack to attach your spinner or maybe an optipac from ultimarc which provides you with a new interface.
