I've bought 50PUS7303 recently. I want to use my HDD with it. It requires 1A so I've bought a y-shaped cable because TV has one USB 3.0 900mA and one USB 2.0 500mA. But when I connect it, light turn on And HDD works for like 3-4 seconds. TV doesn't see it no matter what format it is or connection combinations. Cable has two USB 3.0 tips. Is that the problem? What can I do to use my HDD? (I can use an USB 2.0 memory with ntfs format only on 2.0 socket)
