Product Q&A

Q1: Will using four devices at the same time affect performance?
A: It may. When multiple devices transfer data simultaneously, they share the available USB bandwidth, so actual performance may vary depending on the connected devices and workload.

Q2: Can I connect an external hard drive with other USB devices?
A: Yes. However, using multiple high-load devices simultaneously may affect overall performance depending on the available USB bandwidth and power from the host computer.

Q3: Why is my device sometimes not recognized?
A: Try reconnecting the hub and the device and make sure the connection is secure. If multiple devices are connected, disconnect some and test again.

Q4: Is the cable length suitable for desktop computers?
A: It depends on the location of the USB port on your computer. The cable is approximately 1ft (30cm) — check that it fits your setup before purchasing.

Q5: Can multiple devices disconnect when used at the same time?
A: Multiple devices can be used simultaneously under normal conditions. However, several high-power or high-load devices may be affected by the available USB power and bandwidth of the host computer.
