Both you and Dan are assuming that I actually care about this hardware
and driver enough to read a presentation or watch a video about it.
Sorry, but that's not happening :)

I'm saying these questions as you all need to be asking yourself that,
and figuring out what the proper api is.  That's not my job here.  I was
just pointing out the problems in your original submission that you all
should have caught before sending it out...

good luck!
