We don't have a LG 8.3 and we probably have a mk1 UR22. If you get "Disconnecting a USB audo device.." then either the OTG cable came loose or is faulty (the UR22 is powered by the adapter) or the UR22 got 'banned' from the USB bus for some reason (not by the app). Are you using an OTG-Y cable? If so, we've had many reports of those causing troubles. If you have a powered USB hub, it would be the next thing to try.
