Installation:
NOTE: The pictures shown in the User’s Manual are for demonstration purposes only. Your computer or product may look slightly different.

an available USB port on your computer.
Your USB Hub comes with an additional USB Power Cable. The use of this USB Power Cable is recommended for additional power if
multiple devices or high power consumption devices such as Micro Drives or Bus Powered USB devices are connected to your USB
Hub. To connect your USB Hub with the enclosed USB Power Cable, please refer to the diagram shown below:
3. Your computer will detect and install the necessary drivers for your USB Hub automatically. Once the installation is complete, your USB
Hub will be ready to be used.
NOTE: If you are experiencing any difficulties with your USB Hub, please refer to the Troubleshooting section in this manual.

Troubleshooting:
1. The transfer speed is slow.
Your USB Hub has USB 2.0 Specifications and the maximum transfer speed is approximately 480Mbps. This maximum transfer speed is only
an approximation and may vary depending on the performance of your computer and your USB devices. If a USB 1.1 or 1.0 device is
connected to your USB Hub or if the USB Hub is connected to USB 1.1 or 1.0 port on your computer, the transfer rate will be limited to
12Mbps for USB 1.1 and 1.5Mbps for USB 1.0 devices.
2. Can I charge my USB powered devices (such as USB charger, MP3 player, or mobile phone) using the USB Hub?
Your USB Hub is not designed to support USB powered charging devices and we do not recommend you to charge your USB devices using
your USB Hub. If your USB device can be charged using a USB connection, please directly connect your device to a USB port on your
computer. (NOTE: This function may not be supported by some motherboards, please refer to your motherboard user’s manual for more
details on your motherboard’s USB specifications).
3. The USB device connected to my USB Hub cannot be detected, or cannot function properly.
Please make sure that the USB device you have connected to your USB Hub does not require more power than your USB Hub can supply.
- When the additional USB Power Cable is NOT connected, your USB Hub can supply approximately 350mA to the USB
ports (in total).
- When the additional USB Power Cable is connected, your USB Hub can supply approximately 850mA to the USB ports (in
total).
Please check the specifications of your USB devices and make sure that the total power consumption of the USB devices connected to your
USB Hub does not exceed 350mA. (NOTE: Typically, a flash drive uses approximately 80mA while transferring data, and an optical mouse
uses approximately 80-120mA while in active mode).
If the USB device you have connected to your USB Hub comes with a power adapter, we highly recommend you use the power adapter
with the USB device to ensure that there is enough power supplied to your USB device.
4. I connected the USB Hub to my computer using a USB extension cable and it does not work properly, or cannot be
detected.
If you are connecting your USB Hub to your computer using a USB extension cable and your USB Hub does not work properly, it is
possible that the USB extension cable is interfering with the connection between your USB Hub and your computer. Please remove the
USB extension cable and connect your USB Hub directly to your computer and try again.
