I'm wondering if this is actually like a Sun mouse, and that second
"LED" is an infra-red one. The Sun mice have both LED and sensor
behind a completely spherical lens, one for X and another for Y
position.

The first time my friend Beccy saw an optical mouse, she had to
find out how it worked, and took it apart. Moments later, two tiny
round lenses popped out and rolled away... they're quite hard to
find, being transparent!
(we did find them again!)
