Ubuntu 20.04 cannot find the Hackrf board?

[George Edwards]

Hello GNURadio Community, 

I built a grc flowgraph in Gnuradio 3.9.5 on Ubuntu 20.04 inside Microsoft VirtualBox. I have a HackRF One radio hardware. I installed the hackrf drivers in Ubuntu with command: sudo apt-get install -y hackrf

and confirmed the installation. I connected the HackRF One board to my computer and in the Terminal prompt entered the command hackrf_info and received the response that it does not see the Hackrf board.

And true to form when I ran the flowgraph, I get the following error message:

RuntimeError: no hackrf device matches

Why is Ubuntu 20.04 running inside MS VirtualBox not seeing the HackRf board with the HackRf drivers installed. And, how do I resolve this issue?

Will appreciate any help to resolve this issue.

George
