I got one of these rather nice USB conference phones. It works fine
with Windows/Mac. ALSA gives the following errors:
[336517.162535] usb 1-1.1: SerialNumber: 0023781E0530x010100
[336517.172419] ALSA sound/usb/stream.c:176 10:1:1 : no or invalid class
specific endpoint descriptor
[336517.177029] ALSA sound/usb/stream.c:176 10:2:1 : no or invalid class

[336517.183350] ALSA sound/usb/mixer.c:795 5:0: cannot get min/max values for
control 2 (id 5)
[336517.236151] input: Jabra SPEAK 410 USB as
/devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.1/1-1.1:1.3/input/input13
The microphone and other features are fine, but there is no playback.
I hope I've attached all possible details about this device, but if
there is anything I've missed out, please let me know.
Rich.

The error you're seeing is a bit different from me.
Can you reply with the output of 'lsusb -v'?
I have a suspicion that Linux is fine and that the USB descriptor for
the device is bad. My device has an Endpoint descriptor with
bDescriptorType 0x25, which seems to be an invalid value (should be 0x5).

The attached patch fixes USB audio support for the Jabra SPEAK 410 USB.
The problem, as I understand it, is that the device contains a
Class-Specific Endpoint (CS_ENDPOINT) descriptor before the Endpoint
(ENDPOINT) descriptor. The USB code all assumes that CS_ENDPOINT can
only appear after ENDPOINT. Therefore the USB code divides up the
interface descriptor into "stuff before ENDPOINT" (in
interface->extra) and "stuff after ENDPOINT" (in
interface->endpoint[0]->extra). For this device, this division does
not work.
You can see lsusb for my device here:
http://mailman.alsa-project.org/pipermail/alsa-devel/2011-December/047036.html
Notice the "** UNRECOGNIZED: 07 25 01 81 02 00 00" line which is the
CS_ENDPOINT descriptor.
The solution (which is a hack ...) is to also search interface->extra
looking for the missing descriptor.
For me, this fully enables the functions of this device.
Rich.

Anyone? Tested on two different machines and it fixes the
audio output problem on both ... If I've sent this to the
wrong list please let me know.

The patch looks good. Please run it through checkpatch.pl and provice
a Signed-off-by tag (see Documentation/SubmittingPatches).

The patch looks good. Please run it through checkpatch.pl and provice
a Signed-off-by tag (see Documentation/SubmittingPatches).

Sorry, I should have followed up on this list ...
Tom (in the CC line) opened a bug with Jabra, and they have issued a
firmware update. Unfortunately this update requires some Windows
software to run. I applied this, and it does appear to fix the audio
playback problem, though curiously it doesn't completely fix the
ENDPOINT/CS_ENDPOINT problem, so who knows what's really going on
there.
Anyway, should you want the update it is here:
https://bugzilla.redhat.com/show_bug.cgi?id=766714#c1
Thanks Tom!
Rich.
