So now we also know it"s and internal console problem not caused by an external device. (Unless the router can cause this. You using tpLink maybe or not? ).
I also saw another recent post here on the forum just now.
Exactly the same error with the same messages. Look at the third error row related to the USB manager.
I saw this every time the console crashed and i believe that is what causes the error.
I wish we could somehow reach someone from allen & heath to release a bugfix firmware update for this. These consoles are still around and they work well.
