Logitech Wireless Mouse install???

Right now I have a Logitech marble mouse, a usb with a pc2 connecter. My favorite trackballs were the Belkin ( non optical) with three buttons and two wheels, they fit my hand and suited me perfectly, but I got tired of constantly cleaning them out. I usually use an old serial port trackball ,that I've had forever, on other people's computers, because it always works. (I keep meaning to buy that darn KVM switch!) I don't care for the trackball operated by the thumb, but some people swear by them. I like the ball guided by my fingers. I also use a lot of keyboard shortcuts- just a habit. I mostly use the trackball for surfing.
