Hello,
I have a CamLink original which worked fine under Debian buster. But
then I upgraded to Debian Bullseye. Now I no longer get the vl4 driver
for the device.
Running a Buster VM on the computer, and then redirecting the USB port
inside the VM, this works fine.
But ideally would like to get this working without a VM. Any ideas on
how to debug this issue?
The closest I can see is this bug report:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=966541 - but I don't
get any stack trace in my kernel log files. Also this is Camlink, not
the newer CamLink 4K.
The logs I do get (tail -f /var/log/*.log) after plugging in the device
are:
==> /var/log/kern.log <==

Not sure why it is trying to use it as a MTP device... Is this normal? I
don't see anything about v4l which I would expect to see.
Thanks

The meeting went well, we had some interesting discussions about things to do
for LUV. I had the browser tab open for hours after I had stopped listening.
When I closed the tab at 1:40AM there were still people talking. We should
have these meetings more often.

One issue that was discussed is copying data from the old web site. The above
URL has the Wayback Machine link for the LUV web site. We need volunteers to
go through that and find what's worth copying to the new web site. I don't
think that a 1:1 copy would be a good idea, some things can be done
differently. For example I think that the FAQ should be a page linked at the
top rather than a link in the sidebar that is less likely to be seen. If you
are interested in helping out with this then contact me off-list.
We had at most 26 "users" in the room (I was 2 "users" so I think 25 unique
people). We did use most of the available network bandwidth for the server
when we had more than 6 people sending video streams. If we keep the number
of active video cameras low we could have many more users, I think 50+ is
quite possible. I think that if we promote our next online meeting to Linux
Australia we will be able to handle the load.

During the LUV video meet we discussed having hack nights with BBB for video
conferencing.
There was interest in making the first session about learning the Go
programming language. The idea is that people would join the session knowing
little about it, and just play around writing some code while discussing their
problems with others.
Who is interested in this and when should we run it? I think some evening at
6PM or 7PM would be best or maybe during the day on a weekend. Maybe Saturday
mid-day.
