Init is probably the right place to do that, except I wouldn't
configure interfaces
I am not going to use, because, some times, they are connected to funky things
(like jtag, for example). I used open to do it on-demand. I don't know
if it was the
right decision, but that was the rationale behind it. If you think
there is a better way, proceed :-).
