RO2 RO2 causing gamepad to rumble

Does not happen frequently, but sometimes when I am playing RO2 my gamepad will rumble for no apparent reason. It shouldnt be affected by RO2 because the game doesnt support it...? I have the controller for racing games and keep it plugged into the back typically.



I am using a logitech rumble gamepad f510 with Windows 7 home premium X64.
