I believe this bug was caused by this commit in the kernel: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/sound/usb/quirks- table.h?id=48827e1d6af58f219e89c7ec08dccbca28c7694e
A patch to fix the issue was committed to the kernel 11 days ago: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/sound/usb/quirks- table.h?id=4ee02e20893d2f9e951c7888f2284fa608ddaa35 It appears that the problem is that after the buggy original patch, the snd-usb-audio module takes over the entire webcam and prevents the uvcvideo driver from accessing it. No idea how long it will take Ubuntu to bring this patch into their kernels. In the meantime, I'm assuming you could work around it by doing something like this (with the webcam plugged in) to force the uvcvideo driver to load first: sudo modprobe -r snd-usb-audio sudo modprobe -r uvcvideo sudo modprobe uvcvideo sudo modprobe snd-usb-audio -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1956461 Title: Creative HD720p webcam doesn't work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1956461/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
