[Discuss-gnuradio] Unable to find USRP#0

[Teodora Petrovic]

Hi

Can anyone please help me?  I am using gnuradio3.1.3.
When I try to run usrp_benchmark_usb.py, I get the a RuntimeError:
Unable to find USRP #0.

When I issue

ls -lR /dev/bus/usb | grep usrp,

I didn't get any message.
This is the first time that I connect USRP board to PC.
Please help me.

Thanks a lot.

Teodora
