Title:
  pulseaudio stops responding after plugging Logitech webcam in

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Repro: plug Logitech C270 (one I have) webcam in USB port (others with
  builtin microphone are affected most likely)

  Expected: device hooks up and works properly
  Actual behavior: pulseaudio becomes unresponsive (totem freezes, volume controls work with huge delay, sound is not played at all), dmesg becomes flooded with messages like "7:3:4: cannot set freq 48000 to ep 0x86"

  After unplugging webcam pulseaudio becomes responsive again.
