I purchased my Motu M4 over a month ago and I haven't used it for over 10 hours. Yesterday I was recording with the two inputs, a microphone and a plugged-in a bass where suddenly the screen of my mac had a message that said it had been disconnected. When I looked over the M4 the levels screen was gone and replaced with the MOTU logo and 4 green lines and one red line on the bottom left of the screen. I tried restarting to its factory settings seeing the white dots appear, no hope. I tried shutting it on and off, unplugging and replugging to no hope. I have attached the image of the screen provided it may be useful.
