This concentrator is simple and effective. It splits 1 USB 1.1 port into 4 USB 1.1 ports (be careful, the USB 12Mbps speed is *shared* by all devices connected to the USB port, you will not get 4 12Mbps as intended s ports). I recommend using USB 2.0 instead 1.1, but if you don't need USB 2.0, this hub will do.
