I have tried using several different mice, like 4 so far, on my pc and they all have the exact same issues, one issue is when i use the mouse wheel to scroll sometimes it will work and sometimes it'll go the other way, and the other is when i'm moving the mouse sometimes it'll be at the right speed at sometimes it will slow down significantly. both issues happen far too often and are really getting in the way every time i use my computer. any help would be much appreciated, and if further details are needed i should be able to provide them.
