If you have a conflict between USB RS485 adapter and brltty was created by macsddau@linuxcnc

I use a USB RS485 serial adapter to connect the HY VFD to the LinuxCNC computer. The first time I try to launch LinuxCNC it fail because the USB port was occupied with the brltty process. I try to change some parameters manually in the conf file and finally remove brltty. This solution give some warning at boot.
I finally found the good solution :
Without changing or removing anything, type this in a terminal :

sudo systemctl stop brltty.service
sudo systemctl disable brltty.service

It will remove the conflict.
