No devices found for PlutoSDR

[armen-gevorgyan]

Hello All,

I am struggling to setup my ADALM PLUTO device with qspectrumanalyzer without success so far.
The SoapySDR and SoapyPlutoSDR projects are successfully installed on my host Ubuntu 18.04.5 LTS

The 'soapy_power --detect' command results in the following:
Detected SoapySDR devices:
driver=plutosdr
driver=plutosdr

While the 'soapy_power --info' gives the following error:
[ERROR] no device found in this context.
No devices found!

A similar error is returned with the SoapySDRUtil tool
_SoapySDRUtil --probe="driver=plutosdr,hostname=192.168.2.1"

Probe device driver=plutosdr,hostname=192.168.2.1
[ERROR] no device found in this context.
Error probing device: no device found in this context_

I am not sure what I am missing in my setup as I couldn't find relevant information, so I would much appreciate if anyone can give a hint on this

Thanks in Advance,
Armen
