Please try the following troubleshooting steps:

• Disconnect the hub from your laptop and unplug all connected devices. Wait at least 5 minutes, restart your laptop, and reconnect the hub. Then check whether the issue is resolved.

• Connect the hub to another laptop and check whether the issue persists.

• Confirm that your peripheral devices work properly when connected without the hub.

• Connect a different USB device to the same port to check whether the port is working.

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.
