This looks like the long awaited change in the USB subsystem to enhance
support for device which need a reset after firmware download (like the
Atmel USB ones). I can reproduce your errors with 2.6.8-rc4.

This Fedora kernel seems to be no plain 2.6.7. What's the output of "uname
-a" ?

I've just checked in version 0.12beta15 into cvs. Please try it, if your
kernel is something like 2.6.8-XXX. Otherwise the change won't be active
and I'll have to change the cvs.
