* ALSA: bcd2000: constify usb_device_id.Arvind Yadav2017-08-061-1/+1
| | | | | | | | | usb_device_id are not supposed to change at runtime. All functions working with usb_device_id provided by <linux/usb.h> work with const usb_device_id. So mark the non-const structs as const. Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

* ALSA: MIDI driver for Behringer BCD2000 USB deviceMario Kicherer2014-04-071-0/+461
This patch adds initial support for the Behringer BCD2000 USB DJ controller. At the moment, only the MIDI part of the device is working, i.e. knobs, buttons and LEDs. I also plan to add support for the audio part, but I assume that this will require more effort than the rather simple MIDI interface. Progress can be tracked at https://github.com/anyc/snd-usb-bcd2000.
