if any body has this problem on a lenovo laptop this is what worked for me "Turn off your laptop and remove any cables/devices connected. Hold and press the power button to perform a power cycle for 20 seconds. Wait 5 seconds. Start computer and check if it fix the issue.
You can also go to Device Manager, under USB Serial Bus controller, unchecked "Allow the computer to turn off this device to save power" and disabled fast startup."
