Jeff, Yashi:

I wrote a similar patch to Yashi's. I've attached it.

Pete: have you applied this to linux-mips yet?

This is the first time I've heard of the gadget api, but I'd love to 
port the
au1x00 usb dev driver to a full-featured device-side protocol stack, as soon
as the community agrees on one.

When I wrote this driver, I implemented my own, very limited, device and
function api, as there still wasn't an accepted device-side api. But 
sounds like
maybe that will finally happen.
