I'm thinking about making a custom Arduino-based mouse and I expect not to be the first one to have the idea. Does anybody know what speed I can expect to achieve? Suppose I use a mechanical mouse as a base, meaning I'll have to monitor 3 buttons and 3 axes (X, Y and wheel), debounce the signals coming from the buttons and transmit all that data via USB. How many times per second will I be able to do this, theoretically? Are there any projects which did something similar, and if so, what speed were they able to achieve?

To make a good mouse, I suppose I should at least beat my display's refresh rate which is 60 Hz, otherwise pointer movement won't be smooth. My current (commercially produced) mouse runs at 100 Hz.
