The rabbit whole looks pretty deep on this one. As far as I can
see it fails adding the device because the device already exists
on the bus but this is the first time it added the device and also
I can find no evidence it even created a bus in the first place.
Feels like there is a large piece of my understanding of how
this is supposed to work that is missing. I think we might have
to wait for Richard to return on Monday, how much of a problem
is that from your end?

Thanks,
