Power over USB for K66F

I'm very new to embedded development, so I'm hoping I'm asking in the right place.  I've got a K66F Freedom dev board here,and using Kinetis Design Studio, I've written a simple application to blink an LED on and off.  I have successfully ran the application on the board, over the J-LINK debug interface.  When I connect the J-LINK USB interface to power, the LED blinks.  However, when I connect the other USB interface to power, the ethernet light turns on, but the LED does not blink.  Since I am testing running the application without the J-LINK interface, I can't use a debugger to figure out what isn't working.  Is there something I'm missing here?
