You can't receive packets from a particular up producer in
a converter, the best you could do is to put smarts in the
producer to not send it up in the first place.

I'm can't think of a reason off hand why your converter is
only seeing packets from endpoint 0.  Make sure the other
port is calling ex_tx_up() with the correct handle (first
arg) and that the two ports aren't sharing some structure
that should be per instance.
