I have no luck or ...

Hello everyone, I give you my personal experience with concerning this case.
As for me, I never managed to make it work on a port usb 3, by cons no problem usb 2.
I tried on several different ports but nothing happens.
I tried with ssd (because of the purchase of the product) are not visible to the system (Windows 7 64-bit) than USB 2.
I also tried with conventional hard drives and the result is the same.
For against my usb key 3 work perfectly on ports in question.
I tried with different sizes, a 40GB Vertex 2 and Vertex 3 90GB, neither is visible usb 3, but they are well usb 2.
I forgot, the case was connected directly to the PC one hand and on the other it was connected via "Inateck Hub 4 ports USB 3.0 charging port + 1" ordered here.
