My Razer DeatherAdder scroll wheel does not consistently work when scrolling up or down. When scrolling it bounces around and may go down when scrolling up and vice versa. It has been doing this for awhile and I have been dealing with it, but thought I would reach out to see if there was a fix.
I performed all the tests, firmware, testing on another computer, using compressed air, etc…
(Copied from another thread but was exactly what i have)
