This is the intended behaviour of the current 2.4 code and the 2.6 code
I'm working on will also implement this behaviour.  There is a question
as to whether we want to be able to assign specific devices to virtual
machines when they are plugged in regardless of the port.  This feature
might be added later.

I've only tested the 2.4 code with one device and one front end domain
though so I can't guarantee it actually works.
