Hello,
I have created a quirk that adds support for the Pioneer DJ DJM-250MK2 mixer (acts like a USB sound card, but Vendor Specific Class).
Output (from computer to card) is working: 8 channels, 48 000 Hz, S24_3LE.
Input is not working. I tried, but I was unable to make it working even under an officially supported OS with Pioneer drivers - Audacity or Mixxx see the channels, but there is no signal. It probably works only with Pioneer proprietary application. But I hope that even mere output support will be useful for someone. (it is usable for playback, just not for DVS)

Can anyone review this patch please?
Takashi, could you put this patch to sound-next ? A partial support is better than no support.
