Weewx 4.9.1 usb.core.USBError: [Errno 32] Pipe error

[Claudio178]

Hi,

I just upgraded from Version 4.8.0 to 4.9.1 and can not run weewx anymore because I am getting following error code:

weewx[20874] ERROR weewx.drivers.ws28xx:   File "/usr/lib/python3/dist-packages/usb/legacy.py", line 211, in controlMsg

weewx[20874] INFO weewx.drivers.ws28xx: Scanned 23 records: current=593 latest=651 remaining=58

does anyone else facing this error or know a solution for that?

Thx ;)

The ws28xx driver has been unchanged since v4.6.0 and even that change had nothing to do with its functionality. 

Is it possible that the version of pyusb changed? Or, a different usb kernel module is being loaded? 

Try power cycling, then set debug=1, then restart weewxd. Post the log from restart through the first report cycle.

I've upgraded to 4.9.1 and cannot reproduce the issue. Since I know Claudio178 personally, I know we have a very similar setup and we are running weewx with ws28xx on a raspberrypi4. However, his station is a newer revision. We'll check it out the next few days.

After a while I´ve done another apt update/upgrade of my os and then retried to upgrade weewx, seems to work now. What exactly happened before, I do not know, but this thread can be closed as my problem is solved.

Thx, to you all.
