I've bought a *wireless* USB keyboard. Is it the fact that it has a wireless infra red receiver that makes it not hot swappable? The keyboard itself doesn't even physically touch the PC.

From: Barry Watzman on 5 Dec 2009 12:22 The fact that it's wireless is almost irrelevant, but if you do plug it in after the PC is up, you may have to hit a reset button (may have other names) on both the keyboard itself and the wireless receiver (which, by the way, may be either infra-red or RF).

Generally a wireless keyboard has a microcontroller in it's base receiver that makes the system think there is a keyboard even if the physical keyboard isn't present at all, so yes it should be fully hot swappable within the limitations we've already mentioned, that if the bios needs to detect it prior to drivers loading, it would need plugged in when the system enumerates the hardware after POST.
