You could carefully edit .storage/core.config_entries file but removing and adding integration is safer way. But may loose some customizations, haven’t tried this in a while

Thanks, editing .storage/core.config_entries worked. Feels like a bit of a hack! For anyone trying to repeat I did:

Stop the container.
In the host machine terminal run ls -laR /dev/serial to list which physical USB devices the symlinks are mapped to.
Make sure that your docker config file maps any usb devices you want to use into the container, e.g.

...
  devices:
    - /dev/ttyUSB0:/dev/ttyUSB0
    - /dev/ttyUSB1:/dev/ttyUSB1

Edit .homeassistant/.storage/core.config_entries, replacing /dev/serial/by-id/xxxxxyyyyy with the device mapped above e.g. /dev/ttyUSB0
Don’t edit anything else!
Save and close.
Start the container.

Now zigbee devices all work again.
