Same exact problem as others. I'm using a 3.0 HD and cable, but everytime I turn on my ps4 I get an error code stating it needs to be repaired. USB options are set to always be on, and I'm using the back port.
Clearly this is on Sony's end. I'll check the front ports today, but even if they work, why doesn't the most important port for this very feature (the back one) work? Massive oversight... Please FIX Sony.
