The connection between clicking a mouse button and seeing something happen on your screen is complicated. In simple terms, you need some kind of software process that’ll shuttle data back and forth between the mouse and the computer, between the computer and the software that’s running on it, and between the software and the screen.
More than just data transmission, you’ll also need a way to translate the data between the mouse that knows only the tabletop on which it sits and software that knows only zeros and ones. Multiply that by thousands of device models and throw in the many connection types (PCI, SATA, USB, serial), and you’ve got yourself quite a stew cooking away in your PC.
