Wrong for Mac. We explicitly set LED state from the keyboard bottom half
if necessary (though it stopped working consistently sometime in 2.1
IIRC).

The CapsLock on ADB keyboards is worth a million laughs actually. It
is sticky by hardware, and never sends a key up event, only key down. See
mac_keyb.c.
