Lost USB and 5V power

[prandall@SCH.org]

After 50 successful matches, we suddenly lost the USB power to our CANivore and our cameras,  the 5Volt power to our analog sensors and MX power to our NavX.  We replaced the RoboRio and everything came back up.  Now after the season, we have reinserted our suspect RoboRio to try to diagnose the problem and find that the 5 Volt power to Analog sensors and the MX power are working, but the power to the USB ports is still out.  We have re-imaged the SD card and reinstalled the robot code.  It comes up and appears to run fine but still provides no power to the USB port.

Quick sanity check on my part.

You have a USB camera.  You can plug it into roboRIO A and it works fine.  You plug it into roboRIO B and it no longer works.  Same is true for other USB devices.

Is that correct?  If so, I sent you a message.  Reply to that and we can move forward to get a repair/replacement.  If I'm misunderstanding, point out how and I'll gladly help think through some troubleshooting steps with you 😃

That is correct though I tested it with the CANivore.
