Fix CM730 USB-Serial connection issue

By default the FitPC2i will use brltty when running Debian 11. This will cause the CM730's USB connection to be disabled. Run the following to disable briltty.

 sudo systemctl mask brltty.path

If you get the following error:

 Unit brltty.path does not exist, proceeding anyway.

Then run the following command:

 sudo systemctl mask brltty

Then reboot

 sudo reboot

Now the CM730 should show up as /dev/ttyUSB0
