Yes, I agree that is probably not a wise thing to assume. I think we
should iterate over all the interfaces looking for a data interface if
it is not a union with the control interface. If you don't beat me to
it I will try to get a patch done in the next day or so.

Hey, I am no expert in this :) I have spent a lot of time going over
umodem trying to get an arduino to attach... it is only because of this
that know the code well.
