Please try the following troubleshooting steps:

1. Disconnect the hub from your laptop and all connected devices for at least 5 minutes. Then, reboot your laptop and reconnect the hub to see if the issue is resolved.

2. Test the hub with a different laptop to determine whether the issue persists.

3. Confirm that your peripheral devices function correctly when connected directly to your laptop without the hub.

4. Try connecting a different USB device to the hub to check if the ports are working properly.
