I'm looking for the program that raises the mouse polling rate and any advice you have.
I'm not sure if there is more than one program, or what the latest version is. I gather there is a rate checker program also.

mouse IMO 1.1a
windows XP
intel core 2, 6600

I gather 250-500hz is a fairly safe range.

Does the program change all of your usb ports?

How safe is it? I'm not worried about frying the mouse....I just don't want to damage the comp.
