Looks like you are on 1.3.11 now, no extra plugins- which is good. I'd suspect (a) your USB cable (length? ferrite bead? have you tried other good-quality cables?) and (b) autodetecting baud rate. Select a decent baud rate and try connecting.

Here's more info on USB cable problems:

Uhhm - just curious: Your printer/board(duet resp. MKS) is powered on?
Do other USB devices run with RasPi USB ports?
