Please follow these troubleshooting steps:

1. Disconnect the dock from your laptop and all connected devices for at least 5 minutes, then reconnect everything after rebooting your laptop to test if the issue has been resolved.

2. Check if peripheral devices function normally when connected directly to the laptop without the dock.

3. Try using a different working USB A or USB-C device to determine if the port itself is malfunctioning.

4. If possible, test the dock with a different laptop to see if the issue persists.
