Gqrx don't see interfaces

[MaciejStawiar]

Hi,
I followed the installation guide from installation.md file and everything went good. All the tests mentioned in the guide are passed.
But Gqrx installed on the same RPi don't see the interfaces. I tried with "other.." and then I put all the parameters from the SoapySDRUtil --find :

$ SoapySDRUtil --find

Gqrx opens and when I press "Play" it crashes with info:

gqrx exited with an exception:

More information can be found by launching it from the console.

Running from console gives such info:

Qt has caught an exception thrown from an event handler. Throwing
exceptions from an event handler is not supported in Qt.
You must not let any exception whatsoever propagate through Qt code.
If that is not possible, in Qt 5 you must at least reimplement
QCoreApplication::notify() and catch all exceptions there.

What I noticed is after reboot, both LEDs LD1 and LD2 are on, but when I use SoapySDRUtil they turns off and remain off.

Installed CubicSDR and it also don't see the CaribouLite.

@MaciejStawiar In case you hadn't seen this issue yet: #200 I believe you can resolve this with the commands in step 7, but the rest is maybe worth a review as well. There are slight differences between OSes, though. Hope that helps!
