Have you tried with another computer or device for the problem? As a corrupt driver(which is nearly impossible) can also cause your Keyword to malfunction. You can check it by connection to your Android phone via an OTG cable. If the problem persists you might need to clean the USB connecter on both the end, (male-female)
