thanks - i've tried different USB ports, unfortunately the same problem. I'm not using a USB hub either. I've searched the forums and I can't find any solutions/other people having the same problem. Any other ideas? I've done a re-install of both the firmware and WB - still no better. When I unplug the cable and then replug it, the connection is fine. But after 10 mins or so it loses the connection. Very annoying when trying to edit sounds etc.
