Wmr200: read_device() USB Error Reason:[Errno 110] Operation timed out

[Alessandro]

Hello all,

firstly thanks so much for your work!

As newbie, I'm having a problem running Weewx on Raspi 4 and Wmr200 as weather station.

I installed weewx 3 days ago, and already I have received the error (attached below) twice, that has blocked weewx.

I have solved rebooting the Raspi, but I hope there is a smarter solution. Now I have also changed the usb cable...

Some infomation:

Raspbian version:

PRETTY_NAME="Raspbian GNU/Linux 10 (buster)"

NAME="Raspbian GNU/Linux"

VERSION_ID="10"

VERSION="10 (buster)"

VERSION_CODENAME=buster

Weewx version:

Weewx version 4.1.1

Installed following http://www.weewx.com/docs/debian.htm

Thanks for any hints,

Alessandro
