[vacaloca <ltirado@xxxxxxxxx>]

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. Webcam C310
