This is an excellent product, perfect for my use. it has 7 USB3.0 ports in the front and two USB ports 2.4A load (in the 4A limit simultaneously). I branch of the USB 2.0 and 3.0 and HUB will automatically detect which ports are used and displays a small LED. Very sober, it does not illuminate the room when on duty.
The small problem is that after this device, you can not connect additional cards Players, gender Kingston FCR-HS3 (the various ports on the player are no longer recognized by Windows). I have not tried it on a Mac Mini (since no USB 3.0 ports) so I can not generalize the issue.
