Title:
  C-Media USB headset not working in maverick

Status in pulseaudio package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: pulseaudio

  This device is a generic Plantronics USB headset:

  generic-usb 0003:0D8C:0008.0009: input,hidraw3: USB HID v1.00 Device
  [C-Media USB Audio Device   ]

  It's failing to work on Maverick. When starting Ekiga and placing a
  call, I'll often get "cannot open device" errors. Re-connecting the
  USB adapter does not work (I generally restart Ekiga after doing so,
  too). I was able to get it working, finally, by restarting pulseaudio
  a few times, then starting ekiga, and then un/re-plugging in the USB
  adapter. Before I restart pulse, the USB output and input devices were
  not showing up in padevchooser. Even after they did, it took a few
  restarts and lots of futzing with to get it working again.

  The only thing I found in logs:
  Sep  8 09:46:42 polt pulseaudio[11227]: alsa-util.c: Got POLLNVAL from ALSA
  Sep  8 09:46:42 polt pulseaudio[11227]: alsa-util.c: Could not recover from POLLERR|POLLNVAL|POLLHUP with snd_pcm_prepare(): No such device
  Sep  8 09:46:42 polt pulseaudio[11227]: alsa-util.c: Could not recover from POLLERR|POLLNVAL|POLLHUP and XRUN: File descriptor in bad state

  Using:
  ii  pulseaudio                 1:0.9.22~0.9.21+stable-que PulseAudio sound server

  This always worked perfectly in Lucid.
