I cannot file a bug via ubuntu-bug linux, since I'm running a mainline kernel (4.6.3-040603-generic) to solve another issue related to USB 2/3 transition.
These messages show up in kern.log only when webcam is connected. Video works fine, but microphone does not. lsusb output of offending device: Bus 003 Device 013: ID 046d:081b Logitech, Inc.
