If the indicator LED on your EXPRESSlink 3 doesn't light up green after connecting it to the USB port, first ensure the cable is securely connected to both the USB port and the EXPRESSlink 3. If the connection is good, the issue might be with the EXPRESSlink 3 drivers. These drivers come with your fitting module, so check its installation. If problems persist, try uninstalling and then reinstalling the fitting module.
