Connect to USB Devices
When the dialog box indicates that the installation has finished, your computer is
now ready for USB 3.0 SuperSpeed devices. This card also supports USB 2.0 or
USB 1.1 devices.
If you choose to use the Power Adapter, plug it into an AC power source, and then
connect it to the GEU302’s power jack.
Note: The Power adapter is optional. When used, the GEU302 supplies up to
900mA to an attached USB device.
