[Hackrf-dev] Broken hackrf one

[Andrew Onyshchuk]

Hi Dominic,

It becomes unresponsive only after I try using hackrf_transfer.
After that it is completely unresponsive and only rebooting/reconnecting
helps.

I'm guessing the ARM chip crashes or turns off. Maybe power supply issue?

Thanks,
Andrew
