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
Device Not Working
• 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.
