Error claiming USB interface: Device or resource busy

I have an N800 and am trying to flash it. I am using Ubuntu 910, doing it as root, have tried all 4 usb ports on my laptop, and have even tried mounting the USB, which is not a problem with Ubuntu 910. I have had N800's and N810's and have flashed them using multiple operating systems over the last 3 years. I am stumped by this one.
