OK, that's good info, but temper it with the idea that by default they
*could* (I'm not saying 'do') turn off all 1394 outputs by default and
then only turn them on for people who call and ask, again using the
Phy registers to tell what's hooked up. Why they'd want to be so pissy
I don't know, and it seems that you've got great insight into how it's
actually done whereas I was only a lowly hardware engineer directing
the design of 15 engineers doing 1394 design. I know what the spec is
capable of - heck, my name is in one of them - but how companies use
them is up to people like you.
