Well, we know that firmware is running, so DFU mode is working.  I
guess the next step would be to test the other pieces of hardware
until we find which part is causing the firmware to fail.  It's
probably easiest for us to do this at the GSG lab.

Could you contact me off list with details about where you bought your
HackRF One?

Thanks,
