Tormod Volden lists.tormod at gmail.comHi Jerry, >From this information, I would think there is something wrong with the device bootloader firmware. But please create a new ticket on https://sourceforge.net/p/dfu-util/tickets/ and provide the information that is requested. Note also that the latest release of dfu-util is 0.10 and you are using a fairly old version.
