Use /dev/serial/by-id/ to identify USB devices

[forum1944-hash]

My rtlamr2mqtt works fine. AT least it did until I pulled the Zigbee USB device out for a test of another device.

I lost the rtlamr device. Whan I replaced the Zigbee USB device Linux/HAOS/whatever reassigned my rtlamr device from 1, 2 to 1, 14. I did not discover this for several days. Annoying. Especially when there is a possible fix. Instead of relaying on the dynamic lsusb output of Bus 001 Device 014: could you consider defining USB devices via /dev/serial/by-id/ ? This method of defining USB devices means that software always knows where a device is because it has an unique serial number. It would, I believe eliminate a lot of frustration and, in my case, lost data.

Thanks
