[Hackrf-dev] Broken/Dead HackRF Blue?

[rdwrench]

Have you tried a hard reset??

     https://github.com/mossmann/hackrf/wiki/HackRF-One


    Using HackRF One's Buttons

The RESET button resets the microcontroller. This is a reboot that 
should result in a USB re-enumeration.

The DFU button invokes a USB DFU bootloader located in the 
microcontroller's ROM. This bootloader makes it possible to unbrick a 
HackRF One with damaged firmware because the ROM cannot be overwritten.

To invoke DFU mode: Press and hold the DFU button. While holding the DFU 
button, reset the HackRF One either by pressing and releasing the RESET 
button or by powering on the HackRF One. Release the DFU button.

The DFU button only invokes the bootloader during reset. This means that 
it can be used for other functions by custom firmware.
