A Linux USB keyboard/mouse question

Maybe someone with more history in Linux than I have can answer this question: Do most Linux distributions boot up and immediately recognize a USB keboard/mouse? (That is, they work automatically without the need for any special boot parameters/options.) Or does this vary from distribution to distribution, something that you have to figure out case by case?
