How to debug an unavailable zigbee dongle? | Home Assistant | Page 1

I have a zigbee dongle that was working without any issues until yesterday. I still see it connected to my Linux box, I can reload the zigbee integration in HA, and everything seems to be fine, except that all the connected devices are unavailable.

dmesg output:

Checked the HomeAssistant Core and Supervisor logs. Core shows nothing. Supervisor shows the stick to be recognised:

The primary interesting bit to me are the various brand names:

Sonoff Zigbee 3.0 USB Dongle Plus - this is how I knew my device
Silicon Labs CP210x UART Bridge - this is how lsusb knows the device
Texas Instruments CC2652 - this is how HA knows the device

I did push the stick yesterday accidentally a bit, but the push did not even remove it from the USB socket. I tried HA reboots, but it did not help. The forum search did not help.

The topic is rather urgent as my thermostat is based on a zigbee thermometer and a switch. While I can operate the switch manually, I need to climb a chair for it, and my partner is getting really annoyed. 😟
