Maintenance

To ensure the longevity and optimal performance of your IOGEAR MicroHub, consider the following maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the exterior of the hub. Avoid using liquid cleaners or solvents.
• Environment: Operate the hub in a clean, dry environment, away from extreme temperatures, direct sunlight, and excessive moisture.
• Cable Care: When not in use, gently tuck the integrated USB cable back into its designated slot to prevent damage.
• Storage: Store the hub in a safe place when not in use, protecting it from physical impact.

Troubleshooting

If you encounter issues with your IOGEAR MicroHub, refer to the following common troubleshooting steps:

• Device Not Recognized:
  • Ensure the MicroHub is securely connected to a working USB port on your computer.
  • Try connecting the USB device directly to your computer's USB port to verify the device itself is functional.
  • Restart your computer.
• Insufficient Power:
  • If connecting high-power devices (e.g., external hard drives), ensure an optional AC power adapter is connected to the MicroHub. USB ports on computers typically provide 500mA, which may be insufficient for multiple high-draw devices without external power.
  • Try connecting fewer high-power devices simultaneously.
• Slow Data Transfer:
  • Ensure both the MicroHub and your connected devices are USB 2.0 compatible for optimal speeds. USB 1.1 devices will operate at their native slower speeds.
  • Disconnect other active USB devices to see if performance improves.
• Hub Overheating:
  • Ensure the hub is in a well-ventilated area.
  • Avoid placing heavy loads on the hub, especially without an external power adapter.
