I'm trying to figure out how the power is generated on this board, and it seems to me that there's something missing on the schematic set.
Let's say that I want to power the unit from the Target USB connector.
I put a jumper on JP1, pins 3,4.
On page 2, it seems that if I do that, I'm connecting TARGET_VBUS -> VBUS. From the schematics I've gotten, seems that is going to short pin 6 to pin 2 on U4, therefore rendering it useless for channel 2. Pin 7 will provide +5 to the BoosterPack connectors.
Where in these schematics is the +3V3 generated for the board? I see lots of connections for it, but they all seem to be loads, not supplies.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

So, if I plug this card into the USB port to use it, what powers the board? Looks to me like the processor chip requires 3.3V, so where does it come from???
