It also seems that an <interface type='hostdev'... <source ... where the source is USB couldn't or doesn't use the startupPolicy that would be present in a normal <hostdev mode='subsystem' type='usb'...>... Anyway, I'm certainly not the expert there - something Laine would perhaps be better suited for, but certainly missing from the interface RNG, but is processed in virDomainHostdevDefParseXMLSubsys. It also seems to be a hostdevsubsyspci property as well. What I was looking for was a way for the <interface...> RNG to perhaps make use of the hostdevsubsyspci and hostdevsubsysusb, but some of what goes on in RNG rules is like black magic voodoo ;-)...
