The cable itself may be defective or damaged. Try using a different USB cable to see if the issue persists. If the problem goes away, it indicates that the original cable was the cause. In that case, replacing the cable should resolve the problem. Ensure that the USB cable is securely connected to both the device and the computer or power source. Sometimes, a loose connection can cause intermittent connectivity issues. Try disconnecting and reconnecting the cable, making sure it fits snugly into the ports. The USB port on either the device or the computer may be faulty or dirty, causing the intermittent connection. Try connecting the USB cable to a different USB port and see if the problem persists. If it does, you can try cleaning the USB port using compressed air or a soft brush.
