Ok.

I think it's fine, just the pointers look strange. Would probably be
different once you resolve the middle layer though.

Again, like above, don't worry too much about changing the
device/firmware. I was just pointing out it's duplicate, if that's the
way it is then too bad, but it doesn't really matter.

The more interesting thing here is to change it to use a struct and not
pack it manually.
