Success! As it turns out, the process was actually not so bad. While I
wasted much of the night trying to reverse the protocol, I realized that
what I had come up with was nearly identical to the version 3
documentation.  Trying the version 3 protocol with the device, I found
that it was nearly immediately functional. It seems that while the
initialization procedure has changed, the position report format is
identical to previous generations.

My tree[1] currently has a hacked brute-force initialization
implementation, although it would probably be nice to figure out what
this sequence actually means. Otherwise, it seems support for this device
is a solved problem.

Feel free to give my tree a try. I'd be interested to know whether it
works for you.

Cheers,
