I'm not sure I want to use multiple mouses. What I am trying to do is have one keyboard, one mouse, one vide0 and then use the KVM switch to switch between doing 3 things: Using the mouse and video with the desktop but multiplying the keyboard or using the keyboard, mouse and video with the desktop but not multiplying or using the keyboard, mouse and video with the notebook but not multiplying. I thought I saw a post where someone was doing this but it didn't give the exact connections needed.
