No, it's not a driver problem. It's the circuitry in-between. The Cocolino works fine with the wheel and all if it's plugged directly into the Amiga. But when it's passing through the Autoswitcher, it has a problem recognising the Cocolino at first unless it's unplugged and re-plugged, and the wheel never works.
Oh, and the disk with drivers came with the Cocolino, and they are already installed. :-)
Thanks,
