TI actually has a fascinating app note on the various potential failure modes of ICs in
hotplug situations. I'll have to see if I can find it when I'm back at my
computer. It was a big eye-opener for me.

What the USB
naysayers haven't said though is exactly why USB is not
suitable for keyboards and mice.
Strictly regarding keyboards and mice, one HUGE win for USB over PS/2 is genuine
hot-plug capacity.
I've never personally blown a PS/2 port, but I have worked on computers with blown
ports, and invariably the user/owner was prone to swapping keyboards with the machine
running. I don't kow if that's an odds thing or cumulative damage, but in my
experience the PS/2 port is just not hot-pluggable in the long run.
