Yeah, I was going to say that the above messages are before any of
may changes get run, so it's unlikely a problem w/ my patch...
If the USB device can't get an address on the bus, then it can't
even ask what type of device it is to load the driver.

Thanks for trying though, maybe someone on the -powerpc list knows
of a fix for that.
