Try the enclosed Qt version of your HelloWorld.grc:
HackRFHelloWorld-Qt.grc
But before you do, press the small blue button on the far left hand side
of the HackRF - it's the reset button.
After you hit the reset button, there should be 2 green, 1 orange, and 1
red LED lit.
If a red dot shows up on your gnuradio companion, press it.
I can generate your libUSB error and HackRF errors by running two
instances of HelloWorld at the same time - but I don't get the runtime
error so it may not be the source of your error.
