I use a laptop for work that plugs into a docking station to which my Logitec G5 mouse is connected. I often take my laptop home where I will connect my Logitech G500. To my understanding, these two mice use the same drivers, so there shouldn't be any conflicts. However, I am thinking of buying a non-Logitech mouse for work. I'd like to know that the non-Logitech drivers will work for the non-Logitech mouse while my Logitech drivers will work for my G500 when I take my laptop home.
You can install an unlimited amount of drivers (mouse or otherwise). In reality though, nearly all mice use the same standard mouse driver provided by Microsoft.
