Whee, you're fast ! :)

No, the kernel doesn't support atusb yet.

I'm at the moment cleaning up things that would only get in the way
later, in case anyone else is tracking changes to the driver. So
far, I haven't gotten a reaction to my patches, much as I expected.
so I time out after waiting a polite amount of time before moving
ahead to the next one, reduce the politeness delay a little, etc.

I just wish we had sponsorship for that work. Then I could commit to
beating that whole stack into shape, along with 6LoWPAN, take charge,
and overall move a lot swifter.

I'll send a patch for the RX/TX race today. Then the path should be
clear for splitting the driver tomorrow. After that, Richard should
have all the groundwork ready for merging in his USB skeleton. I
hope he has time :)

This still won't produce a usable driver, because of the missing
interrupt EP code in the atusb firmware, which is next on my list.
If things go well, it all should work early next week.
