Sorry, I don't know what that error means. However anyone wanting to use 
"dfu-util -U" should look at http://docs.openmoko.org/trac/ticket/676 - 
dfu-util upload seems to cause data corruption. I tested on a GTA01Bv4, 
so it would be useful if someone could repeat my test on a production 
Freerunner and then add a note to the bug.
