There are a couple of ways you can "plumb" devices and objects together.
For devices you can use a qdev bus if you have a strict parent/child
relationship between A and B. Or you can use a "link" property to
manually wire up the devices/objects. Or use can use object composition
(device A creates a child object B).
But I think it depends a lot on what you are actually modeling and you
are not sharing a lot of information on that ;)
