Have you tried this > on any other boards like Big or Blaze? I have a Blaze here, but haven't been able to get the external ports to power up. I don't have schematics nor a strong interest to get that fixed myself, as I can test my code just fine with the Blaze's internal camera and the devices that do work on the Jetson. I'm using the firmware file that was posted recently: xhci-tegra 70090000.usb: Firmware timestamp: 2014-05-02 02:22:50 UTC, Falcon state 0x20 If things work for you with the same sources, .config and firmware, I can only think of the hw being different (other hw revision?).
