I'd personally suggest an Icbox USB hub, they offer various models, powered and non-powered, just bear in mind devices over a hub share the bandwidth of the host port(it won't necessarily share evenly between devices), regardless of the model you choose. If the system has USB 3.0, a 3.0 hub will give you 5 Gbps across all the devices, vs 480 Mbps on a USB 2.0 port and hub.
