I consider that unlikely because of the power requirements of the Motors
and the NXT unit. I don't know how much the new motors pull, but the
"old" motors took 250mA @ 9V under load. According to the USB specs, the
port should provide 500mA @ 5V. Most USB port actually fail to provide
this power level, so 300mA @ 5V is a better bet.
So, A USB powered NXT would mean: NO MOTORS - PERIOD ;-)
Hey, and that would be boring, wouldn't it?
