I love the size of this item. Works like a USB hub. like but not like the photo. I tried connecting USB controllers but nothing helped. I tried: Ematic Switch wired gamepad, original SNES controller with USB adapter, wired Logitech f310, wired Xbox 360, wireless Xbox 360 with USB adapter and wireless Logitech Rumblepad2 with USB adapter; none worked. I needed a working Magic NS adapter (available here at Revain). Almost all tested gamepads worked. With Xbox 360 Wireless I can connect 2 gamepads at the same time (I only have 2), I think it can connect up to 4.
