- Restart your computer and try connecting the hub again.
- Verify that your computer's USB 3.0 drivers are up to date. Most operating systems handle this automatically, but manual updates may be necessary in some cases.
- Connected Devices Not Working or Recognized:
- Ensure the device is properly inserted into one of the hub's ports.
- Try connecting the device to a different port on the hub.
