: You could compile the kernel with "options USB_DEBUG". Then there is a
: sysctl "hw.usb.uaudio.debug" that you can set.
:
: Else you could also try compiling a kernel from the USB perforce project, and
: see if that works better.
The root problem isn't in the sound system or usb system, per se. The
root problem turns out to be that the volume button on this device
will mute things if you press it, but won't unmute it if you press it
again or spin it. There are special features that uaudio doesn't yet
support for this device.
Once I started keeping my paws off that button, things just worked...
