[Hackrf-dev] HackRF One won't power on and connect

[Dominic Spill]

Hi Craig,

It looks like you've been fairly thorough with your testing, switching USB
cables, etc.  Have you confirmed that the working HackRF works with the
same USB cable, PC and port that the broken one fails with?

Does it look like there is any damage to the USB port?  Or anywhere else on
the HackRF?

Thanks,

  Dominic
