Question Can either FireWire-based PowerCore be used a hub for other FireWire devices
Yes, that is possible. However please note that we advise against using it with bus-powered FireWire devices -- which are powered via FireWire -- as the PowerCore is not able to provide that power for bus-powered chained FireWire devices. In fact, connecting any bus-powered FireWire device to the PowerCore could damage the PowerCore and void any remaining warranty!
