We have been using it for over 4 weeks, and it has been working fine.
Are any of the LEDs on the navX lighting up at all? If none of the LEDs light up at all, even at initial power-on, then the navX is not getting power. The most likely cause of this is swarf in the various pins of the roboRIO, which can result in shutting down power to the output rails of the roboRIO, including the MXP port.

We had the above problem at one point. Vacuuming out the swarf that had fallen into the unused roboRIO I/O pins fixed the problem for us. As insurance against future occurrences, we taped over all the unused roboRIO output pins to help keep debris out of the roboRIO.
