Public bug reported: 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_v4l2 24576 1 gspca_main videobuf2_common 49152 2 gspca_main,videobuf2_v4l2 videodev 208896 5 gspca_main,gspca_zc3xx,videobuf2_v4l2,videobuf2_common lsusb output is: Bus 002 Device 002: ID 8087:0024 Intel Corp.

ZC0305 Webcam Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub 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! --- 1) https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/media/v4l-drivers/gspca-cardlist.rst ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872634 Title: Webcam Z-Star 305b doesn't work in Ubuntu (again) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872634/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
