Due to its how its implemented on the motherboard, standard PS/2 isn't hot swappable. Any support for hot swapping is the exception, rather than the norm.

I always thought it was a bit ironic that VGA and RS-232 cables (with D-sub connectors) could be mechanically attached with screws, even though they were hot swappable. Yet PS/2, which used screwless mini-DIN connectors, wasn't hot swappable.
