Hi Peter,

I recently reinstalled weewx and the WS6in1 driver on a RaspberryPi 4 
(previously on a rPi 2) and hit the same problem
I solved it by installing the crcmod library via the apt command:

$ sudo apt install python3-crcmod

Not sure why the pip3 command didn't provide the needed files, this wasn't 
needed originally.

I am in the process of updating the readme.txt to add this and focus on 
python3 installation.
As the driver seems stable I'm also going to up it to version 1.0 (but no 
code changes from 0.9 other than changing the version number)

Hope this helps

Bob
