Appreciate your clarifying that for me.

The problem is that the USB hub only supports host->peripheral communication, not peripheral ->peripheral. I tried it and it doesn't do anything. It would be ideal if it was more like an network hub that allowed all ports to talk to each other, but that's not the case. Here's a diagram for of my setup for those who had trouble with the pictures:

What I haven't show is an alternate setup where the 770 plugs into the hub master port so you can connect more than one device. It's just a matter of taking a mini-USB->male cable and plugging the male end into the female end of the the wire going to the 770 (still need the male cable plugged into the hub for power though) and the mini-plug into the hub.
