Thanks a lot for your help.
I am now one step further: the station is now correctly detected. But I run
into the error below almost immediately.
NOTE: the error shown below occurs when I try to run weewx in a docker
container (using pyusb 1.0.2). To rule out problems related to docker, I
also tried on another computer, running Linux Mint 18.3,
python 2.7.12, pyusb 1.0.0b2 and starting weewx as root. The error message
is slightly different but produces the exact same stack trace: USBError:
[Errno 32] Pipe error.
Any clue on what I am doing wrong?
Thanks.
