Just got a new GO 510 so registered and set up MyDrive Connect on my Mac, which it did fine and my GO 510 initially connected with the software okay. Noticed that there were some updates available, so left these running as they were going to take 25 minutes or so. When I returned to check if they had completed, my device was no longer connected and has failed to connect ever since, which was about 3 hours ago. It attempts to connect but then suggests that the USB cable isn't connected correctly. Now, why can it one minute be successfully connected and the next become disconnected and totally unable to reconnect? Any clues, please?
