  1. Does anything else work in the USB 2.0 slot?
  2. ya, it's working
  3. because usb 2.0 only supplies up to 500 mA and usb 3.0 supplies up to 900 mA, it may be that the single usb connector that your portable HDD uses is not supplying enough power. I am guessing here and am not certain. Do you have one of the Y usb cables to connect it to two ports?
