I'm using a new-ish Apple keyboard here. It works well except that (a) about=
 twice a day or so, the control n=C3=A9e caps lock key misses a key up event=
 (tapping it again solves it), and (b) the fn key (and therefore the things a=
ccessed by it) does nothing.

I originally had all sorts of problems with the thing, including protocol er=
rors and the pi rebooting or freezing, dependent on the order things got plu=
gged in. I then realized I was under-powering the pi. The most common USB po=
wer sources put out around 500 mA; the pi wants (from memory) 700-1200 mA, a=
nd really seems to be happier at the higher end of that. I went out and got a=
 2A USB charger and things improved dramatically.
