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.

Thanks for the patch. The changes look OK, but could you fix trivial coding issues reported by scripts/checkpatch.pl and resend?
