I came up to this question while i noticed a remark on logitech's site. My mouse is a logitech optical USB but i am running it on PS/2. They say - on their site - that i won't be able to take advantage of the 800 dpi resolution which the USB 'll give 2 my mouse. What's the deal with 800 dpi and how it impacts the mouse performance ?
Also, Will this mouse draw more power when it is USB connected rather than PS/2 connected. I know that the power consumption is nothing 4 the mouse in both cases and i am not worried but i just wanted 2 know this info 4 my knowledge.
