Hello,
I got this message today so I'm following the instructions:

sbaudio: no idea what's going on..., contact 
linux-usb-devel@lists.sourceforge.net

I hooked up the Byterunner USB 5.1 Channel Audio Adapter:
http://www.byterunner.com/cgi-bin/cart.cgi?store=byterunner&cart_id=9681830.6602&product_name=UA580&user-id=&password=&exchange=&exact_match=exact

It works playback and record in windows, but only playback seems to work 
in linux.  The company claims USB compliance as follows:
USB specification v1.1
USB audio device class spec v1.0
USB HID class spec v1.1

It does say that only 2 channel playback works in on Mac systems... 

I attached some info below that might help if anyone is interested.  
Otherwise, if anyone knows a good linux compatible USB microphone audio 
input device, that would be great! ;)

Thanks,
-John
