I just found that the USB 3.0 connector on the back panel is not function. I had tried to link up the +5V pins from the USB 3.0 connector on the side to that connector, I connect a USB HDD to the connector on the back then the HDD spin but signal is not through, of course the player can not detect It is a HDD connected. I believe this connector is just a dummy and not functioning at all. Is any one tried that? Also if Futeko know about it? I have problem if this connector don't work as my AVR is blocking the access of the USB 3.0 on the side.
