Exiting...
the error indicates that the weewxd process does not have permission to
read/write the USB-to-serial device. make sure that the user running
weewxd has read/write permission to /dev/ttyUSB0 (which is probably a
USB-to-serial adapter).
for example, if user 'weewx' is running weewxd, then put the weewx user
into the dialout group then restart weewxd:
sudo usermod -aG dialout weewx
sudo systemctl restart weewx
see the section about reading/writing to devices in the wiki article "what
you need to know about permissions":
