• Make sure that the device is fully inserted into the
correct port on the USB 2.0 4-port hub.
• Plug the device into a different port on the USB hub. If it
still doesn’t work, test the device by connecting it
directly to your computer.
• Verify that you ran the Setup or Install program for the
device.
• Make sure that the device appears in Device Manager.
For more information refer to “Verifying Devices are

device works before plugging in the next one.
• Each USB port is equipped with over-current
protection. Should a USB device draw more current
than the USB port can supply, the port will shut down.
