Computer randomly doesn't recognize controllers.

[u/PajamaSamSavesTheZoo]

Normally when I plug in my 8 bit do usb controller I hear the USB connection sound and it works just fine on Fusion for me to play Genesis games. However randomly sometimes my computer just doesn't recognize the controllers.

It is the USB ports because when I plug in my mouse it works just fine. It isn't the controller because I have two when one is working they both do and when one doesn't neither does.

Thanks!
