I got programming docs for this gizmo some time ago.  It's a uhid0 in regular
mode, which sends keys, and a ugen0 for which I have some developer docs.

Has anyone else tried to build a driver for this?  It looks like it's an easy
userland driver to write, and I may be able to build a pretty decent version,
but if someone else has done it, I'd rather not bother.
