4. Setup

The Gembird USB 2.0 4-Port Hub is a Plug & Play device, requiring no additional drivers for most operating systems.

Connect the Hub: Locate an available USB port on your computer. Insert the integrated USB-A connector of the Gembird hub into this port.
System Recognition: Your operating system will automatically detect and install the necessary drivers for the hub. This process may take a few moments.
Connect Devices: Once the hub is recognized, you can connect your USB devices (e.g., mouse, keyboard, flash drives) to the four available USB ports on the hub.

The hub draws power directly from the USB port of your computer. No external power adapter is required for typical use.

5. Operation

Once connected, the Gembird USB 2.0 4-Port Hub functions as an extension of your computer's USB capabilities. You can connect and disconnect devices from the hub as needed.

Data Transfer: The hub supports USB 2.0 speeds, allowing data transfer rates of up to 480 Mbps. This is suitable for most peripherals and storage devices.
Power Distribution: The hub distributes power from your computer's USB port to the connected devices. Be aware that connecting multiple high-power devices (e.g., external hard drives without their own power supply) may exceed the available power from a single USB port, potentially leading to unstable operation or devices not being recognized.
Hot-Swapping: USB devices can be connected and disconnected from the hub while the computer is running, without needing to restart.

6. Maintenance

The Gembird USB 2.0 4-Port Hub requires minimal maintenance.

Cleaning: Disconnect the hub from your computer before cleaning. Use a soft, dry, lint-free cloth to wipe the surface. Do not use liquid cleaners or aerosols.
Storage: When not in use, store the hub in a cool, dry place away from direct sunlight and extreme temperatures.
Cable Care: Avoid bending or twisting the integrated USB cable excessively to prevent internal damage.

7. Troubleshooting

If you encounter issues with your Gembird USB 2.0 4-Port Hub, please refer to the following common solutions:

Device not recognized:
- Ensure the hub is securely connected to a working USB port on your computer.
- Try connecting the device directly to your computer's USB port to verify if the device itself is functioning correctly.
- Try connecting the hub to a different USB port on your computer.
- Restart your computer.
Slow data transfer:
- Ensure both the hub and the connected device support USB 2.0 or higher. Connecting a USB 1.1 device will limit speeds to USB 1.1.
- Avoid connecting multiple high-bandwidth devices (e.g., multiple external hard drives) simultaneously to the hub, as this can share the available bandwidth.
Devices losing connection or unstable:
- This can occur if the total power draw of connected devices exceeds the power supplied by your computer's USB port. Try disconnecting some devices or using a self-powered hub if you frequently connect high-power devices.
- Ensure all connections are firm.
