Please try these troubleshooting steps:

• Disconnect the hub from your laptop and all connected devices for at least 5 minutes. Reboot your laptop and reconnect the hub to see if this resolves the issue.

• Test the device with a different laptop to see if the issue persists.

•  Verify that peripheral devices function normally without the hub.

• Try using a different USB device to check if it works properly in the ports.

If all of the steps above cannot help you locate and resolve the problem, please contact Anker Customer Support for further assistance. Briefly mention the steps that you’ve already tried for a faster solution.
