Copy the myFocuserPro2Linux AND myFocuserPro2Linux.ini files to a user folder on your Linus system (like a folder under the desktop)


=====================================================================================================================
UBUNTU-MATE
You must be a member of the group tty
Use menu, administration, users and groups, manage groups, tty, properties
and ensure that your name is checked, then click OK

chmod +x myFocuserPro2Linux
or you can right mouse click the file, properties, permissions and check allow executing file as program

I had to right mouse click file and chose run as adminstrator
It seems it cannot connect to tty0 device without admin priviledge
