I tried to get a Logitech QuickCam USB camera working, but unfortunately, it is
not detected by user space (Cheese, MPlayer).

Could you please try it with Camorama?

Thank you for the suggestion. At first, I only saw a black image, but changing the
resolution made it work. See the status below.

1.  does *not* work

     a)  160x120
     b)  176x144

2.  works

     a)  320x240
     b)  352x288

Try this patch:

https://patchwork.linuxtv.org/patch/53043/

It probably fixes the same problem you are experiencing.

It indeed does. I cherry picked it to Linus’ master branch, and it fixed the problem.

Kind regards,
