Hi!
Thanks for the nice software. Here is a bug report in the form of a
patch. Why not pull-request? Because this patch does not solve the
problem but works around it. The affected code path has so many
indirections and in-band signalling that I didn't find the underlying
cause.
Support for Brymen BM869s multimeter has been broken for me for a few
years. In Fedora Linux, it last worked with the 5.10 kernel, if I
remember correctly. In Ubuntu 24, it does not work.
Sorry for the crude approach. Unfortunately, time constraints do not
allow for proper investigation.
