Paul, ? There appears to be a situation when JMRI does not recover from these errors but continues to retransmit the ERROR and INFO message, eventually (in this case after about 120 attempts everything comes to a holt except that the recovery messages continue to grow !
I put a screen shot of the console messages at the point where this started in the photo section but basically it looks like:-
ERROR - Auto recov from 61 81 EO. Retransmit 0 times (liusbethernet.LI...¡¡.Receive thread)
ERROR - Auto recov from 61 81 EO. Retransmit 0 times (liusbethernet.LI...¡¡.Receive thread)

Hopefully this might lead somewhere !
