Yes, as far as I understand the problem is that the id= would work on
the ioh3420 device itself, while what is needed here is to name the
secondary bus of the ioh3420, which I haven't found a way to name from
the command line.

Maybe an even better solution would be to have default names for
everything, if not specified, from a user friendliness perspective? 

I suppose this is a more general issue of sensible default values
though, but the fact that it is easy to create devices which cannot be
referred has caused me some confusion from time to time.
