which brings power to the host. Now what's the point of a self-powered USB Hub if I need to do that?

Do I still need that cable in addition to my USB Self-Powered Hub? I also read that I can hack my Hub or Cable to do the same thing as that cable does. Can anyone please explain how I would do this? I was under the impression that it would work without that special cable......

Thanks
The powered hub provides power the "output" of the hub to power your peripherals (keyboard, hdd, etc.)
You still need to get 5Volts to the 770. What I did was take my hub apart, and solder a small jumper from the 5 volt line on one of the "output" ports to the 5V line on the "input" port. No special cable required. Others have used cables, like the one you linked to, to steal the power from one of the outputs. This is probably safer if you are not comfortable with modifying your hub.
