I'm currently working on Alsa support for the Behringer BCD 2000, a DJ control surface (http://www.behringer.com/EN/Products/BCD2000.aspx). Unfortunate this device does not act as a standard class device. Since proper technical documentation from Behringer is non-existent my work is based on analysis of the USB data stream. Current status: - driver supports midi input data for all controls/buttons that are able to send midi data (some of tje controls do not send out data but are hardwired to the analogue circuitry, eg. headphone volume etc.) still todo: - get the midi-output working to allow control of the LEDs on the control surface. - cleanup of the code (mostly remove debugging stuff) - documentation The unit has also a 4 channel 24-bit audio interface; at the moment I have little interest in trying to get this audio interface operational. If anyone else on this list has a similar device and would like to test it please let me know so I can send patches. Regards, Frank.
