I've bisected down to the commit that is causing this bug: edcd3633e72a1590c4cf46befe5e6cd03b5aec3e - ALSA: snd-usb: switch over to new endpoint streaming logic
However, the logic that caused this regression is in the following commit: 8fdff6a319e7dac757c558bd283dc4577e68cde7 - ALSA: snd-usb: implement new endpoint streaming model I attempted a simple revert, but it is not possible. The following commit is also involved: d399ff9593e088d33fb38f5206c6427825892baa - ALSA: snd-usb: remove old streaming logic This last commit just removes the obsolete unused code, which was causing a kernel compile error. I'll continue to work on this bug and send details upstream. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1018020 Title: Logitech webcam not working To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1018020/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
