Hubs make it easy to connect or disconnect devices without disturbing others.
Rather than the daisy-chain type of connections where you plug devices into each other, with the FIRE VUE Hub you plug in devices without effecting the chain. The 6 port Hubs can also be tied together to create an unlimited amount of ports. The supplemental power supply adds needed power when devices do not supply it. IEEE-1394 or that have a compliant card and software. FireWire HUB gives you the ability to easily add or remove devices without interrupting other devices on the bus.
