I have one ;-)

I think the simple numbering is far more straightforward, because this
way the bus doesn't need to know about what devices can be connected
to it. The way that Olaf's patch does it, every new device type that
may get added in the future needs both a device driver and a change to
the bus code, while the other way, we can simply add a new driver.
