my zwave usb stick was working fine in ttyACM0. then i added a zigbee stick from here and now HA no longer talks to my zwave devices throughout the house.
cd /dev/serial/by-id
ls -al

what can i do next to at least get zwave working as usual? afterward, how to add zigbee? i did follow the direction here https://www.zigbee2mqtt.io/getting_started/running_zigbee2mqtt.html but that didnt work.
