Since I switched from Rpi 4 to Rpi 5, I sometimes get this error from weewx. And then I am forced to reboot it.

You specified /dev/ttyUSB0 as the port the Vantage is connected to. Unfortunately, it's not there.

This can happen when the Vantage disconnects for some reason. It will often reconnect at a different port. This is particularly common if you use a serial to USB port converter. 

See the wiki guide on Troubleshooting Davis stations. In particular, the section David cp2101 converter problems and the following section, Installing a udev script.
