USB Serial via ttyGS0

Configure systemd to start a getty on ttyGS0
As root do the following
# ln -sf /lib/systemd/system/serial-getty\@.service getty\@ttyGS0.service
# systemctl start getty\@ttyGS0.service 
Note: the file "/lib/systemd/system/serial-getty\@.service" is a text file that contains the configuration for the serial port.
I have heard that there may be a conflict with the mass-storage driver running on the same USB port
