6. Troubleshooting
If you encounter issues with your DockCase Visual Smart USB C Hub, consider the following:
- Display or Charging Issues: Ensure your host device's USB-C port is full-featured. A full-featured USB-C port supports Power Delivery (PD) charging, DisplayPort Alt Mode for video output, and USB data transmission. If your port only supports data transfer or charging, certain hub functions may not work. Look for a lightning bolt symbol next to your USB-C port for Thunderbolt 3/4 support, indicating full functionality.
- Desktop Computer Compatibility: Desktop computers are generally not recommended for use with this hub for expanding the screen and PD fast charging. USB data transmission may also be affected. This is due to the nature of desktop USB-C ports, which may not be full-featured, and cannot be resolved by modifying hub settings or firmware updates.
- Connection Stability: Ensure all cables are securely connected. Loose connections can lead to intermittent functionality.
- Power Requirements: If connecting multiple power-intensive devices (e.g., external hard drives, high-resolution monitors), ensure a 100W PD charger is connected to the hub's PD input port to provide sufficient power.
