No way at all with kernel 2.6. I'm sorry to say this. It is a known
"feature" of some M-Audio USB devices (Audiophile USB, Quattro, and
obviously Duo), that they violate the USB specification. They don't
work on kernel 2.6, which requires compliance.  There currently isn't,
and probably, until M-Audio fixes this, never will be support  on 2.6
for this device.

If your device has this symbol printed on it or on the box: 

http://www.usb.org/images/headermain/original.gif

then you might want to contact the USB-IF (http://www.usb.org/) and
tell them about the violation and misuse of the USB logo. But my
Quattro doesn't have this symbol, so the USB-IF cannot do anything
about this. M-Audio obviously didn't do official USB compliance tests
with the Quattro...

ciao
