From 8f7f3ab15e0873a9b04d5a38ef1d33831aaf609d Mon Sep 17 00:00:00 2001 From: Alexander Schremmer Date: Thu, 3 Jan 2013 12:59:07 +0100 Subject: 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.

It fixes two things: 1) A kernel panic caused by incorrect allocation of a u8 variable "bootresponse". 2) A noisy dmesg (urb status -32) caused by broken pipe to an invalid midi endpoint. It is also a little cleaner because there is no need for a new QUIRK_MIDI type as suggested by kernel developers, since the device follows exactly the MIDIMAN protocol.

I don't have the device so I haven't done a full analysis, but it seems userspace (both udev and pulseaudio) got confused when a card was created, immediately destroyed, and then created again. However, at least one person in the bug report (martin djfun) reports that this patch resolves the issue for him. It also leaves a message in the log: "snd-usb-audio: probe of 1-1.1:1.1 failed with error -5" which is a bit misleading. It is better than non-working audio, but maybe there's a more elegant solution?

Right now, the clock source points to the internal clock (0x81), which is also valid. When the external clock source (0x82) is selected in the mixer, and the rates mismatch (if it's free-running it is fixed to 48KHz), xruns will occur. Set the clock ID to the clock selector unit (0x81), which then allows the validation code to function correctly.
