Hi all.
Followed up this thread to fix the WXT5x0 driver from GitHub and got bit
forward but got jammed to another issue, apparently something to do with
python3 (?)
Running Ubuntu server 20.04.1 LTS
Startup log looks like this;

Exiting.
Any clues how to get forward? The system works OK with the simulation
driver so this might be still to do with the WXT5x0 driver.
