Right .. so (I think) you still need to resolve this
AIRSPY_ERROR_NOT_FOUND issue. When you use "airspymini" (bogus), it
doesn't even try to find your AirSpy device.
I don't have any AirSpy hardware, so can't test anything, but Googling
for that error found:
https://github.com/airspy/airspyone_host/issues/40
I'd start there...
