Hello,
I have a problem with my USB headset. A short summary:
It doesn't support sample rates of 8000, but it does support 16000. Some
applications (e.g. Ekiga) try to access it with 8000, so they fail. The
Ekiga developer(s) think, the translation/conversion should be handled
by ALSA.
The details can be found here:
<http://bugzilla.gnome.org/show_bug.cgi?id=329609>
Question: Is their claim valid? Should I file a bug report to ALSA?
Regards, Daniel

If you are getting "cannot submit datapipe for urb 0, err = -28" then it
means you MUST have enabled USB bandwidth checking. Please make sure
it's really disabled.
Try:
$ grep CONFIG_USB_BANDWIDTH /boot/config-`uname -r`

OK, that's completely bizarre, and I've never seen another case like it.
Also, plughw should handle all sample rate conversion, it's very strange
that alsa-lib resampling fails...

I guess it can only handle sample rate conversion when it knows that it
has to do sample rate conversion. So, maybe the hardware reports the
wrong sample rates?
Here's some output from lsusb -v, which (to me) seems to say: "Hey, I
can do 8000". What it doesn't say is "I can do 16000", but that may be
handled correctly by converting some other sample rate to 16000.

Seconds after I wrote that, I had another idea. I plugged the headset
out of the monitor's hub and into the PC directly. Now it does work with
8000. Obviously, that's just a work-around, not a solution. And I'm not
sure what that means for you, though :)

Bug in the USB subsystem, probably. Try the latest kernel.
