Does it work in DFU mode?  To enable DFU mode, hold down the button
labelled "DFU" and press the reset button.  If that works, it should
show up as an NXP LPC4330 DFU device.

If DFU mode works you can use it to update firmware to restore
functionality to your HackRF One.  If it doesn't work, we'll need to
run through some more tests.
