Husbz-1 zigbee setup

Greetings all!
I have a Samsung tablet PC (core i5 4gb ram) running lubuntu 18.04 as my openhab server.
I am running openhab 2.4 installed as a package with the recommended Zulu Java. I have a husbz-1 zwave and zigbee combo USB which I got to zwave (ttyUSB0) working fine on - but I now want to add zigbee to my network and I can’t get the zigbee side (ttyUSB1) to show up to add the controller. I have added it to my and the “EXTRA_JAVA_OPTS” and restarted multiple times but I cannot get ttyUSB1 to show up as an option in the configuration so I can use the zigbee radio.
