I have not yet solved this issue of the com issue, but I have some new information in trying to better understand the problem. I also have a USB Logitech (C920) webcam connected to the Pi, I use FSWEBCAM to grab an image every 5 minutes via a cron job. If I disconnect the USB webcam, the system runs with no issues for days, but I soon as I plug the webcam in then weewx usually crashes within 6 hours. I also tried adding udev rules for defining my FTDI USB -serial converter but it did not work following the steps from the weewx wiki, I also found other info that said to place the rules under /etc/udev/rules.d/ of which I tried that also failed. I also did testing on a Pi 2 and Pi 3 both had the same results.
Any suggestions would be greatly appreciated.
