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?).
