Joe, This seems to happen when several USB devices are active at the same time. Do you also have a USB scanner, or any external USB disk drives running? Disconnect other USB devices and see if that fixes the problem.

But the transfer failed because it ran out of space. Any help will be appreciated why this may have happened. Joe Lazzaro
