When I work with a mouse I want to use hot corners. When I work with the Trackpad, I don't. Is there an option for this? The hot corners should only work if I used my mouse to activate it. I'm not optimistic, but I can't be the only one who wants it to work like this.
You cannot differentiate what kind of mouse/input device triggers hot corners. To the computer, a pointing device (mouse, trackball, trackpad, etc.) is a pointing device and all give input the same way so there's no way for it to differentiate what is actually moving the mouse. Hardware settings for each different device (such as tracking speed for a mouse vs a trackpad) are a different story.
