We recommend the following guidelines:

•Do not transfer data to or from multiple high-speed devices, such as a digital camera or scanner, at the same time.

•If speed degradation does occur, close other programs that use a USB device to improve device performance.

Troubleshooting

•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 Installed” on page 13.

•Disconnect all devices from the USB 2.0 4-port hub and reconnect them, one at a time. Check that each 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.
