I’ve had to hard reset my controllers (both Zwave and Zigbee) a few times now, haven’t really found a cause but it’s usually been around times when updates were applied. It almost seemed to me like the device wasn’t released by the old container and that needed a hard disconnect to force it. IIRC logs just showed a generic can’t connect to device error but no sign of what had the device locked. First time I did some investigation, the few times it’s happened since then I just unplugged and reconnected the usb device, restarted the container and it worked after.

I haven’t had it happen for a while at least.
