Please try these troubleshooting steps:

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

2.Check whether your peripheral devices work normally when connected directly to your laptop without the hub.

3. Try connecting a different USB device to the same USB-A port to determine if the issue is with the port or the device.

4. Test the hub with a different laptop to see if the problem persists.
