Title:
Webcam Z-Star 305b doesn't work in Ubuntu (again)
Status in linux package in Ubuntu:
Incomplete
Bug description:
My webcam Z-Star 305b was supposed to work out of the box [1], but it
doesn't work in bionic. It only shows a black screen.
I've read lots of threads and tried some suggestions, but
unsuccessfully.
At present, I'm using bionic x86_64 with kernel 5.3.0-46-generic,
before that I tried it with 4.15.0-96 and some previous versions.
lsmod |grep gspca output is:
gspca_zc3xx 57344 0
gspca_main 24576 2 gspca_zc3xx
videobuf2_vmalloc 20480 1 gspca_main

videobuf2_common 49152 2 gspca_main,videobuf2_v4l2
videodev 208896 5
gspca_main,gspca_zc3xx,videobuf2_v4l2,videobuf2_common

I tried several ubuntu-version to figure out if the error was
introduced recently into the kernel but couldn't find any working
version
I've tried cheese, vlc and guvcview.
I've tried LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libv4l/v4l1compat.so
cheese which made change cheese change it's error message and vlc to
not work at all.
I would appreciate any help, because I'm completely lost. :-(
Thanks in advance!
