7. Installing the Board

Assuming that you have already installed the USB host adapter (including drivers) on a computer
running Windows, installing the hub is fairly simple.

1. Plug in power from the power supply to the hub. The power supply must meet the

requirements specified in Section 4.

2. Plug a USB cable in the USB0 port, and connect the other end of the cable to the USB host.

After a while the GoodLink LED (D15) will start to blink. This means that the enumeration
process has successfully completed and the hub is now ready for use.

You can check the driver installation in the Device Manager window. To check whether the
hub is correctly installed in high-speed, choose the

View-Devices by connection command

in the Device Manager window.

3. Plug in devices to the downstream facing ports. After these devices are properly

enumerated, the green LEDs will turn ON.
