Does this also show up in 2.6.25-rc8 without -mm?

I thought I fixed this already, I don't see what slipped into -mm that
would have caused it to come back.  Time to run some more tests...

Oh, also note that binding and unbinding the main "usb" driver is not
encouraged, or even supported.  I'm amazed it works, as this is not
something that any "real" user would do as it makes no sense at all
because we have no "alternative" drivers yet for the main USB device.

thanks,
