I am stuck, have been working for the last 2 days to upgrade my Pixhawk to -rc3. many failed attempts using MP 1.2.80, 81, and 82. MP fails after unplug USB then plug back in MP fails with "Can not communicate with board" error.
Qcontrol said it successful upgrade but then stopped at 90% and failed. Not sure what code was loaded.
Any help would be great. I do not know what to try next.

Hmmm...the need for a 2A powered USB port was NEVER mentioned in the documentation! Maybe that's why I've had nothing but problems with the Pixhawk. Not to mention, the documentation is sparse at best.

@David,
I found that neither my PC nor my laptop USB ports had sufficient current capacity to run a full up PX4 FMU, IO, GPS, outboard compass, and Spektrum PPM receiver (using a regular receiver and a PPM encoder takes even more power). The FMU leds would light up as if the PX4 was functional, but I could not communicate with it. The solution was to use a powered USB hub with at least a 2 amp supply. I have no trouble now communicating with my full up PX4 when using a powered USB hub. Also, keep you USB cables as short as possible.
