A solution that WORKS was suggest to me on the Octoprint forum. sudo systemctl disable brltty
It seems like I am not the only person who has WASTED countless hours because you have decided to ship this version of Mate with the "BRLTTY" service enabled.
BRLTTY as I'm sure you are aware has a conflict with ttyUSB0 causing ttyAMA0 not to connect to any USB devices. A major issue to many CNC router and 3D printer users.
Might want to rethink shipping the service disabled in the future.
