ALSA: usb-audio: Add support for Creative BT-D1 via usb sound quirks
Support the Creative BT-D1 Bluetooth USB audio device. Before this patch, Linux had trouble finding the correct USB descriptors and bailed out with these messages: no or invalid class specific endpoint descriptor Now it still prints these messages on hotplug: snd-usb-audio: probe of ...:1.0 failed with error -5 snd-usb-audio: probe of ...:1.2 failed with error -5 snd-usb-audio: probe of ...:1.3 failed with error -5 But the device works correctly, including the HID support. The patch is diff'ed against 3.8-rc1 but should apply to older kernels as well. Signed-off-by: Alexander Schremmer <alex@alexanderweb.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
