It seems that after the last reboot you are not getting any logs anymore. Are you sure, you selected the right port? You could try with `tail -n 100 -F...

Very strange that there are no new logs. Try to reinstall the driver and reboot the GX device after.

The serial starter is not starting the driver. Probably your adapter is not recognized anymore correctly. Check with `lsusb`. Are you using a USB hub? If yes, connect the USB...

What is the output of `lsusb`?

Your USB to serial adapter is not recognized. That is the problem.

Do you still need assistance?

Any updates?

Please post a picture of your cabeling. You know that you currently can connect only one battery per serial adapter? See also https://github.com/Louisvdw/dbus-serialbattery/issues/142.
