I've bought a new dj'ing control surface, Behringer BCD2000, which currently does not seem to be supported using the Alsa-driver (current hg snapshot). The device is basically an USB soundcard (4 in, 4 out) and most likely a MIDI interface connected to the device's knobs, buttons and leds. I noticed that bInterfaceClass is set to 255 instead of 1 as I would expect for an audio class device. Perhaps some quirck is needed to get this device recognised? If someone could give me some hints where to look for and where to start at hacking this device alive in linux that would be wonderfull.
