I have come across a problem whereby if I am running a print from my MAC through the USB, it will all come to a stop if I add or remove any USB device from anywhere on my system, from attaching/detatching my mobile, turning any device on that is connected via USB. The Machine Control Panel says that it is trying to force a reconnection, but nothing happens. It is particularly 'frustrating' if you are near the end of a longish print.
Is this a known thing?
