This sounds plausible and I'm with Jeff here.
For me as the driver author it's the smallest change.
I will put it like this:
on cable gone:
on cable reconnected:

Is that ok, i.e. what all drivers do or should do?

For the problems that applications might have (i.e. sockets being
blocked etc.) another solution should be found.
And as Jeff pointed out, this should be a central solution and
not be implemented in drivers.
