Sorry got cut off, proper drivers. Using Claude, it's telling me.. TerramasterOS doesn't include the cdc_acm kernel module, which is required for the ZBT-2 (and most USB serial devices like Zigbee/Z-Wave dongles). I can see the ZBT-2 hardware when running dmesg | grep -i -E "usb|tty|nabu|303a|cp210|serial" | tail -30 but HA doesn't see it and the hardware (ZBT-2) has a red light.

Figured it out, has to install this manually, enable the cdc_acm driver reboot, and it worked to connect (green light) the hardware, now im trying to get it found in homeassistant running in docker..
