You were misinformed. If there is no ranges property, the child nodes are not directly addressable from the bus above. If the ranges property is present, but empty, then there is an identity mapping between parent and child bus addresses. So you probably want to add ranges; to the parent node. -- David Gibson | I'll have my music baroque, and my code david AT gibson.dropbear.id.au | minimalist, thank you.
