WMR200 getting USB Error Reason:[Errno 110] Operation timed out

[peredst...@gmail.com]

This RPi3B+ have been running Weewx 4.2.0 for a long time and then a few months ago it just started getting USB-errors. I have two other RPI3B+ running WMR200 and they have not this issue. So what is wrong with this one?

I have tried to restart Weewx, rebooted RPi, unpluged WMR200 USB but to no success. I tried to read the code in wmr200.py to figure out where/why this timeout occurs. I even upgraded this RPi to Buster (from Stretch) as the other two are running Buster.

Note really sure what the next step would be.

Yes, I know that WMR200 is not supported in newer versions of Weewx and that I'm running older versions now.

It seemed that the WMR200 had gone into some semi-hung mode where the display was showing strange values and graphics.

A hard reset (power reset) of WMR200 solved the problem. But it had to be power-less for at least 30 sec for it to reset fully.
