[QUOTE=BradWright;2625167]I wonder what this thing actually uses the USB port for (power maybe?). As far as I know, the only thing that can be done with my TV’s USB port is upgrading the firmware with a thumb drive. I don’t think it has any other uses, so I wonder if this would work on my TV. Any suggestions/advice from all you CE gurus?[/QUOTE]
According to the girl in the video it’s for power.
The guy in the videos on the page olyteddy linked to confirms it’s for power only.
You should watch those videos as well as I think this gadget looks impressive.
