Hi, I use Weewx since 2017 with Excelvan WH2310 without problem. Last week, I decided to update raspian up to buster and since this, I got problems with Weewx.
Daemon weewxd can not communicate with USB station after start or after some times... I unplugged/replugged the USB cable and after, data read seems to work again... I used WH2310 add-on update for Python3 from git otherwise weewx does not start (I tried standard wh23xx driver in vain, even with last updates 0.41 from git). *Dec 14 16:54:54 pi3b weewx[1954] INFO weewx.engine: Main loop exiting.

I did an import yesterday for same problem (connect the usb on PC to retrieve 10 days of data via SmartWeather tool, export to CSV, import data on Pi ....). I have to do it again :-( At this time, nothing is stable. So I* add weewx monitoring tool by cron which check time of last modification of daily pictures and if too old (6mins), I restart weewx after reseting USB device. :-/* Any idea with USB problem ?
