Answer
Yes you can use a USB hub with the ColorSource console. The port(s) on the console are standard USB 2.0 ports, meaning they will support up to 0.5A draw. You can use a hub as long as you do not exceed this level of current. It is highly recommended by ETC to use a powered hub (USB hub that has its own power cable) in this case. A powered USB hub will supply 0.5A on each of its USB ports, while an unpowered hub will only supply a total of 0.5A across all ports.
