I put the rule in

Yes I rebooted the router after making the change.
In the logs it shows modem manager has failed to connect to ttyUSB1 but I still can't use gcom correctly until modem manager is not connected.  Once modemmanager is disabled the ttyUSB1 works fine with gcom.

That one looks right to me.

Do you reboot ModemManager after updating the rules file?

In which file (exact path and filename) are you adding the rule? The
rules file should be prefixed with 77-mm, 78-mm, 79-mm or 80-mm.
