Jack uses ALSA; that driver code was tested only with Jack, and

I guess you are not root.
bmAttributes 37
Transfer Type Isochronous
Synch Type Asynchronous
Usage Type Implicit feedback Data
I guess
this is one of the devices that use implicit feedback
synchronization, which is very buggy in the current driver. As far as
I know, only Jack works with these devices.
Huh? How could that work with JACK if it doesn't with ALSA? Btw, this is what i get when trying to start JACK
with it:
ATTENTION: The capture device "hw:0,0" is already in use. The following
applications are using your soundcard(s) so you should check them and
stop them as necessary before trying to start JACK again:
jackd (process ID 2341)
Even more bugginess. Maybe try the other Jack.
A patch series that should fix the bugs was posted on alsa-devel:
