Got a build error:
  sound/usb/caiaq/audio.c: In function ‘snd_usb_caiaq_audio_init’:
  sound/usb/caiaq/audio.c:808:28: error: ‘USB_PID_TRAKTORAUDIO2’ undeclared (first use in this function)
  sound/usb/caiaq/audio.c:808:28: note: each undeclared identifier is reported only once for each function it appears in
  make[3]: *** [sound/usb/caiaq/audio.o] Error 1

Missing change in device.h?
