From the photo it looks to be compatible with a wall mounted power supply; e.g., Digikey T313-P13P-ND (5V, 550mA, $4.85) or similar. The 5V connector appears to be a 1.7mm receptacle with center positive. Mike, please correct this if I'm wrong about the connector.
Whatever the connector, you should be able to get one easily and fit it to whatever you want to use to power the USB device and the Chicklet.
The more important question on changing <R78> remains to be answered:

It would not be sensible to simply delete the rule; to minimize hazards FIRST will probably want to restrict the type of external power supply allowed. Or maybe they'll just keep the "power-passive" requirement as it has been.
Obviously I'm just speculating here -- if anyone has actual knowledge of FIRST's intentions, they probably should keep it quiet until kickoff.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
