so i just got this game last night and i hopped onto a server only to find out that my weapon wanted to fire on its own or swing by its self, so i got off hoping it would be better the next day (today). now what i have realized is the my character would swing the flashlight but not his fists, so idk what the problem could be.
i have already tried cleaning out the USB port where the mouse is plugged in, i tried restarting that game and my computer, and my drivers are all up to date. any help/suggestions would be greatly appreciated, thank you. 
oh and its only in this game, i went onto CS:GO and didnt have this problem.
