The Hama USB 2.0 Hub is used for connecting up to 4 USB devices such as a mouse, keyboard, printer, USB memory stick, etc. to one USB port. It is bus-powered (i.e. power supply via the USB socket of a PC/notebook). It has as integrated USB cable for connecting to a PC/notebook. The hub has a greater distance between sockets, making it easier to plug in wider USB plugs. This high-speed hub is also backwards compatible with the slower USB1.0 full speed.
