[Hackrf-dev] Not recognized USB

[Dominic Spill]

Is there any relevant output in dmesg when you plug in the HackRF?

The DFU method loads firmware in to RAM and immediately runs it.  One
you've done that, before running hackrf_spiflash, you can run
hackrf_info to see if the HackRF is recognised.  Does it show up?
