[SOLVED] Logitech G502 hero

That mouse has a wheel option on it to go between smooth scrolling and step scrolling with a notch feel, I am guessing you hit that button. It's the button closest to the wheel. The one bellow it is for DPS adjustment.
I know that
I tried two modes free run and normal
by the way
I returned the mouse and will buy a new one from differnet seller
