it's not designed to be hot swappable, and apparently there was ONE model of mac that
you
could blow the chips on easily that way, however, it does usually work, at worst the
mouse
gets terribly slow on some systems. i just swapped keyboards a little while ago with
the
system on, in the middle of typing something up (the keyboard got flaky, finally too
flaky
after a couple of days). having said that, apple says don't do it, and i don't know
what
model blows the chips, i don't have one of those and it was an earlier machine, besides
which i can solder so it doesn't scare me too much. you aren't supposed to, but it
usually works, except for the one chip set that really reacts badly to the abuse.
having said that, i once designed something and had to change the connector wiring
because
my boss insisted on hot plugging one of the cables (on a $250K piece of equipment when
it
was all together, the part i designed was just part of a large unit), it blew the chips
consistently with power off on part of the machine, back through 2 or 3 chips
sometimes, i
finally had to change the power pin so it got power from the unit it was plugged into
so
that that unit wouldn't see signals when it was off. adb isn't nearly that fragile on
most machines, but it is best not to do it all the time, though one rarely has a
reason to
hot plug it. people have a strong tendency to hot plug things, which is why newer
standards allow for that (often by adding substantial circuitry), though any one who's
played with audio cable's with their amp on certainly knows it can be ugly.

Time to stop beating around the bush. Beat the bush _itself_.
Give it a good thrashing, and say "bad bush!" in a loud stern tone.
