Key specifications

How to use

Connect the hub to an available USB 3.0 port on the host computer using the integrated cable or supplied connector. Once connected, the operating system should recognize the hub automatically and make the additional ports available. Attach USB devices to the hub ports; for high-power devices or multiple simultaneous high-draw devices, consider using a powered USB hub or connect devices one at a time to ensure stable operation. Safely eject storage devices from the host before disconnecting to prevent data loss.

Recommendations

For sustained high-speed transfers from external drives, connect the hub to a native USB 3.0 port on the computer rather than through an upstream hub. Avoid using multiple high-current devices at once when the hub is bus-powered; for reliable operation with several power-hungry peripherals, use a dedicated powered hub or a device with an external power adapter.
