Bug description:
  This USB headset doesn't seem to support sample rate polling, similar
  to this issue:


  == The problem ==

  Every time something goes to interact with the device (playing a sound
  file, opening the sound panel, opening web audio/video), a 10 second
  pause is encountered, where dmesg prints out two messages:

    usb 2-1.2: 2:1: cannot get freq at ep 0x83
    usb 2-1.2: 2:1: cannot get freq at ep 0x83

  Once the sound is playing, everything is fine.  These sample rate
  polls don't seem to keep happening.  After waiting for maybe 30
  seconds after sound is playing, future interactions will again trigger
  the pause.

  This 10 second pause can introduce other subtle problems.  For
  instance, google hangouts will sometimes timeout waiting for the sound
  device to respond, and the browser tab will crash or not fully load as
  a result.  The sound panel often also will not display the device in
  the list of choices, and you will have to close it out.  Sometimes
  restart pulse audio to get it to recognize the headset again.

  == The solution ==

  It is simple, add this USB ID to the
  sound/usb/quirks.c:snd_usb_get_sample_rate_quirk function.
