Do these two devices work any differently. They're both powered externally? Will both of these be equally effective at eliminating a ground loop?

A USB hub will probably tie all the grounds together, so that won't help you break your ground loop.
Update: I just checked a Belkin F5U701 hub with my multimeter (in continuity mode). The grounds of all the USB ports are tied together and tied to the ground of the power supply.
