Title:
  QinHeng Electronics CH345 MIDI adapter triggers error

Status in pulseaudio package in Ubuntu:
  Incomplete

Bug description:
  Cheap oriental MIDI adapter starts up with the following error, but
  works as expected.*

  E: [pulseaudio] module.c: Failed to load module "module-alsa-card"
  (argument: "device_id="1" name="usb-1a86_USB2.0-MIDI-00-USB20MIDI"
  card_name="alsa_card.usb-1a86_USB2.0-MIDI-00-USB20MIDI"
  namereg_fail=false tsched=yes fixed_latency_range=no ignore_dB=no
  deferred_volume=yes use_ucm=yes card_properties="module-udev-
  detect.discovered=1""): initialization failed.

  The device:
  1a86:752d QinHeng Electronics CH345 MIDI adapter

  Of course i'm not sure whether this is a PA problem or an ALSA or UDEV
  bug.

  Ubuntu 14.04.2 LTS
  Pulseaudio 1:4.0-0ubuntu11.1

  *  works almost as expected: there is one physical input and one
  output, but in ALSA one input and two outputs appear.
