Yes, here's the most complete set of messages from dmesg. I have not noticed any difference in the order which the steps are taken to turn on the device and boot to NOR and to plug in the cable.

The other cable I have is for a blackberry, but I get the same result. Note - this seems to be a dfu-util problem, I am able to connect with neocon.
