for a MX 700 Cordless optical Mouse, Which Port?

USB or PS/2?

i ask because i want to know if i'll have to get the USB capable KVM switch, or if i dont take a hit in performance if i just get the PS/2 only.

USB, it's faster if you're a gamer.

im a gamer, but the switch will cost about 70 bucks vs. 30 bucks for a standard switch w/ integrated cables...

PS/2. I remember reading some post that proved that the mouse can't even take advantage of the PS/2's bandwidth, so using USB is useless.

Ethier port is fine, however be warned that many PS/2 KVMs will only support the plain-jane parts of the PS/2 protocol, so any extra buttons aside from the standard 3 on your mouse may no longer work. I've had this happen many times. You would not have this issue with a USB KVM......

As for the USB vs. PS/2 debate...

On PS/2: Your PS/2 controller samples movement data coming from the mouse anywhere from 20 to 200 times per second (Hz). The default sampling rate in 9x OSes is 40hz, default in Windows 2000 is 60hz, and the default in XP is 100hz. 2k and XP both allow you to change the rate from 40hz to 200hz via the mouse's Device Manager properties window. 9x requires that you use a thrid party tool. (like PS2Rate)

On USB: Your USB Host Controller polls input devices (KBs, Gamepads, Mouse, etc...) 125 times per second for data. This rate is set and cannot be changed.

Could you actually notice a different between a USB mouse updating 125hz and a PS/2 mouse at 200hz? I highly doubt it....

Use whatever port works best for you!

i agree with stevewm... use whatever port is convenient to you..

for me, i only have 2 usb ports.. so i have my keyboard in one of them and a CF card reader in the other.. that just leaves my ps/2 port open and i just use that one.. don't notice too much of a difference in performance in everyday stuff and game related things..

I have mine connected to the USB port.
