Hi - no, plug & play was not enabled on the machine it is currently connected to, so I enabled it just now. However, I do have other USB devices plugged in to a 4 way USB hub all of which work as did plug & play devices. In any case, it still does not work and does not show a new device message or anything. Plus, as I said, I tried it on another computer (newer) and connected directly to the USB connection with no change.
