I am convinced that this specific gadget it is USB 2.0 speaking of output ports, and only input this is somewhat USB 3.0 compatible speaking of cable (input).
Possible I am the only one with eyes and able to see that output ports are plain USB 2.0 connector with just four pins.
Do not waste your time with downloads and hardware inspection, some one in China aiming to rip-off people by selling a gadget this coming with allot fake advertising.
If you are smart and quick, just request full refund from the Ebay shop that you got it from.
And if you crack it open USB2.0 ports plugs they come with all PCB contacts as to were USB3.0 but from other end of its connector there is only four pins.
Optical delusion so most people to be fooled again in case of visual inspection
