The case is accompanied by his leaflet in French as well as a CD containing drivers for using the Ethernet port. I am very satisfied with the product because the Ethernet port provides access to content from other connected USB device. Tested on a laptop and a fixed, it works perfectly provided that you have installed the drivers first.
The USB Hub works great I could connect a mouse, a USB key and joystick simultaneously and everything worked. For thirty euros this device is quite recommendable although I regret that the cable is so short, however, a USB extension cable may allow you to use it more comfortably.
