IntelliMouse Optical: Any Advantage Using USB over PS/2?

[Nighthawk69]

Hi there...

I have a Microsoft IntelliMouse Optical which has support for both USB and PS/2 connections. I am wondering, besides ease of use, is there any advantage of using the USB connection over using the PS/2 port for this mouse?

Thanks!

Not really. It can depend on your BIOS. If your BIOS gives you legacy USB support, then a USB mouse can be used with some DOS boot utilities - otherwise - PS/2 only will be seen in DOS. Whatever turns your crank. The mouse will work the same.

Thanks! That's what I needed!

Event packet data flight time, including interrupt handling, is faster from an USB port than from the ancient PS/2 keyboard controller unit. It's only a matter of milliseconds, but it's enough to give the mouse cursor movement a smoother feel.

Thanks! If the mobo likes it on the USB port with the bus overclocked, I'll put there. If not, it stays on the PS/2 then

Thanks again!

USB is better for FPS games.
