Title:
  usbaudio: unit X: unexpected type X - parse_audio_unit() fails

Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux” source package in Precise:
  In Progress
Status in “linux” source package in Quantal:

Status in “linux” source package in Raring:

Bug description:
  For some usbaudio devices, an unexpected type can cause parse_audio_unit() to fail.
  This results in a message like the following:

  [544717.685926] usb 1-1.5: new high-speed USB device number 14 using ehci_hcd
  [544717.779149] usb 1-1.5: New USB device found, idVendor=1235, idProduct=8014
  [544717.779154] usb 1-1.5: New USB device strings: Mfr=1, Product=2, SerialNumber=3
  [544717.779157] usb 1-1.5: Product: Scarlett 18i8 USB
  [544717.779160] usb 1-1.5: Manufacturer: Focusrite
  [544717.779162] usb 1-1.5: SerialNumber: 00009F2B
  [544717.833068] usbaudio: unit 51: unexpected type 0x09
  [544717.833568] usbaudio: unit 52: unexpected type 0x09

  The commit 61ac51301e6c6d4ed977d7674ce2b8e713619a9b, allows for this
  type to also be handled, allowing the usbaudio device to operate.

  This was fixed in v3.9-rc4 and beyond; therefore precise/quantal and
  raring are affected.
