just not hot-pluggable in the long run.
I think that's mostly a design issue. In the MCU projects I've
worked on using a PS/2 keyboard for input, I've never had an issue
with hot-plugging. Quite often, I'll plug in a keyboard after the
MCU program has started. Since outputs are all supposed to be open-
collector, I don't see how damage could occur, unless it's from
something like ESD.
