Great! I plan to get out a new release with this and a few other minor
changes tomorrow.

I can tell you -- you have v3 :)

In the 0.4 software it will print out the protocol version right after
it loads. The reason I know you have v3 though is that you're hitting
the code paths for initializing the trackstick, which don't exist in the
v4 protocol support.

v3 and v4 are just what I'm calling them, based on the order in which I
encountered them. It's entirely possible that v4 hardware predates v3.
But they almost certainly have different firmware. The distinctions are
that the data they emit is formatted differently and that they use
different register layouts internally. There may well be other
differences too, but those are the ones I know about.
