This looks like the expected output from dfu-util.  Did you do
anything after this?  Reset the device?

After downloading the firmware to the device, it should jump straight
in to it and run it.  Does anything appear in lsusb output? (It will
show up as an OpenMoko device).  Which LEDs are on?

Thanks,
  Dominic
