Additional Notes:
Some USB 3.0 devices require direct connection to host ports. 2.4Ghz wireless devices (keyboards, mice, etc.) may not work around USB 3.0 ports. Try using a USB 2.0 connection instead.
If you find the computer not recognizing the device after it has been plugged in, try unplugging the UBS port and re-plugging it back into the computer.
