Zaheer knows - he should reply :)

One thing he ran into is that the message happens on every bus reset, so
also when other devices get plugged/unplugged.  Do you think the element
should filter these, so that it specifically only messages for
disconnectcs/connects on its devices ? If not, what's a good way to
relate it to the actual device being used getting disconnected ?
