Is there any advantages using usb mouse over ps2 mouse? thanks.

USB provides a higher speed connectionfrom device to PC. Make sure that if you buy a USB mouse, that it is a Microsoft Product, I've seen nothing but problems with others where they require additional software to be installed. Keep the PC 'CLEAN and TIDY'.

Hi, I personally like the USB vs PS2 as it does seem to have a quicker response. Besides, I think most USB mice come with a PS2 adaptor, so you can try it both ways to see which you like better. Also, you may want to consider an optical USB mouse. I have tried them and will never go back to a ball tracking mouse. Much more sensitivity (that takes a little bit to get used to) but I sure won't go back. Right now I am experimenting with a MS wireless setup. Basic keyboard with a few hot keys for mail, media controls, etc. Mouse is optical with the adaptor for USB or PS2. So far I love it. No wires to get hung up on anything else on my desktop and it was on sale for $69.99 at Comp USA (free for me as I got a gift card for Christmas). Good luck!

PS/2 and Serial mice work just fine when you boot to DOS and have the standard Mouse driver. Not so with a USB mouse. The required USB drivers are too big for DOS mode. Knowing that the USB drivers are a large block of code should tell you that supporting a USB mouse is more processor overhead than a PS/2 mouse. PS/2 mouse drivers are built into the kernel drivers and usually still work when Windows is going down the tubes. USB interface drivers are usually the first to hang. As for data rate, sure you can push more date over a USB interface. But that is not needed. The mouse sends packets of data that describe its movement. The same information gets transfered regardless of the packet rate. In theory, the PS/2 interface can handle over 300 packets per second. Each packet is 3 or 4 bytes. The mouse can only send a maximum of 200 packets per second. Tests show that there is no detectable difference with mouse movement until the rate is restricted to below 40 packets per second. And no detectable problems with packet maximum rates as low as 25 per second. The default operation of the PS/2 mouse as of DOS 5 was reduced to 100 packets per second to reduce system overhead. So bandwidth is not a consideration. The only advantage of a USB mouse is the theory that you can have fewer cables. You can chain a mouse with other devices and have fewer cables running to the system. (But by my count you still have the same number of cables going somewhere, just not as far.)

KEEP to the standard Ps2!. Usb = installing lots of annoying drivers! and not having a mouse on a fresh install of a windows os until drivers are installed Very annoying!

Has this world gone mad? What are people thinking when they design computer equipment! Some little idiot shouted "USB is the future" and the whole world followed in his footsteps. Do yourself a favour and try this yourself! Get the following to test: (Dont try this at home if u an idiot cos u will blame me for your pebkac) Genius Netscroll+ (PS2 ONLY!)

Sure optical USB mice are smooth on the mousepad... but they are not smooth into the port on yer pc. PS2 ballmice are a little rougher on the pad (get a velt pad) but they are awesome in yer pc :) What is the point of having 100gazillion DPI mouse if it isnt pushing that amount back to yer pc? If somebody happens to have a USB Rate program please be so kind as to mail it to me.-and my apologies to USB users if it exists. uber_777@hotmail.com If you have an optical mouse that does 200Hz+- and doesnt skip when u do a 360 degree turn in Quake3 please post its name model etc here :)
