I'm running Home Assistant in a VM (OS v16.3, Core v2025.12.2) on my UnRaid server (Pro v 7.2.2), and passing through the Zigbee USB dongle to it. Yesterday I accidentally disconnected the dongle, but when I re-connected it, the ZHA integration would not recognize it even after I restarted HA. Restarting the VM didn't help. Only after I rebooted the UnRaid server itself did it start working again. Is there a less invasive way to do this than rebooting the entire UnRaid server?

make shure you configured the usb using the device_id instead of usb port.

Not sure how or where to do this.

#

for zha, you would look in settings>system>hardware>all hardware and look for tty, your dongle is listed. Copy whole /dev/serial/by-id/xxxxxx path to your zha port configuration

#

to check the path in unraid go to shell and enter: ls -l /dev/serial/by-id/ this will show your usb devices
