However, if a USB keyboard is not plugged in when the system is powered up, some BIOS' will not subsequently recognize one if it is plugged in later. It depends on the bios, and, also, on some of the settings inside the bios to enable/disable USB keyboards (this is bios and therefore motherboard dependent). MOST USB devices are hot swappable.

From: Barry Watzman on 4 Dec 2009 22:56 You can USUALLY "hot swap" a PS/2 keyboard. But not always. As I mentioned with respect to USB keyboards, it is bios and motherboard dependent.

I'd rather have people spread the notion of PS/2 not being hot swappable like USB is, in order to prevent more lost motherboards due to blown PS/2. I don't hot swap mine. If I need to move my favorite keyboard and mouse (both PS/2) to another machine, I power off to do it. I'm also careful with Firewire, because there are enough sad stories around, to be suspicious of the design of the Firewire connector system. There are theories about how failures occur, but no proof. USB, I don't have concerns about that, with at least the hot swap end of things. The only motherboard I'm careful with, is my P4C800-E Deluxe, due to it having the failure-prone ICH5R. If I use the USB on that system, I plug the USB device in with the power off. There have been enough failures of ICH5/ICH5R without me adding to the list. I don't have to worry about that with the other machines. My current VIA based system has been trouble free on USB. Paul |
