In addition to Vince's suggestions, check and see if there is a competing process trying to access the serial port. Try:
*sudo lsof /dev/ttyUSB0* Finally, if none of that works, make sure you have connectivity to the logger in the Vantage. See the wiki article *Establishing connectivity <https://github.com/weewx/weewx/wiki/Troubleshooting-the-Davis-Vantage-station#establishing-connectivity>* .
