Your weewx.conf could call the device any random string you made up... but if the os doesn't call the /dev/whatever the same thing it won't work end to end. You need to have the device in weewx.conf match whatever your version of your os uses. Just match'em up so weewx.conf reflects what your os calls the device.
Generating all locales would take a super-long time, FWIW. I just do US on mine. One question though - are you using a USB logger from your Vantage or a serial logger and a serial-to-usb converter ? Reason I ask is that the device might be different as a result. I just plugged a usb2serial adaptor into my pi4 and saw a /dev/ttyUSB0 device created when I did so. You should see dmesg and lsusb and /var/log/messages reflect what you have plugged in. As always make sure you have any peripherals plugged all the way in and nicely seated. Some transcripts below. Hope this helps. (... from dmesg ...)
