snd-bcd2000

Linux driver for the Behringer BCD2000 DJ controller (1397:00bd) Official Behringer Website

Dependencies:

• snd_usbmidi_lib
• snd_rawmidi

Usage:

• Either assure that kernel sources are available under: /lib/modules/$(shell uname -r)/build and execute "make" in the snd-bcd2000 folder, or use DKMS to build the kernel (see Ubuntu DKMS).
• Either directly load the module using insmod snd-bcd2000.ko or use modprobe snd-bcd2000
  if the module has been installed into the kernel's module tree.

If it does not work:

• Make sure you have all build tools, e.g., gcc and make, and the kernel headers installed. For Ubuntu: apt-get install build-essential linux-headers
• If you can build and load the module, but it doesn't work, check the output of dmesg. E.g., if there are errors like snd_usb_bcd2000: Unknown symbol snd_rawmidi_receive you have to load the dependencies of our module first. In the above case, execute modprobe snd_usbmidi-lib.

Troubleshooting

If audio is enabled, device initialization sometimes fails with the following error in the kernel log:

snd-bcd2000: usb_submit_urb failed: -28
snd-bcd2000: could not start pcm stream

This is likely an issue with bandwidth reservation on the USB bus. As a workaroud, the driver now disables the capturing from the device by default as most people just use it for playback. If you see this error or you need to capture audio from the device, try the different USB ports of your PC - especially switch between USB 2 and 3 ports.

There is also a repository:

(https://github.com/CodeKill3r/BCD2000HIDplus)

with an alternative firmware for this device which claims to provide a standard USB audio interface so you would not need a special driver. However, to use this firmware you need special hardware tools.
