GRC cannot find USRP N210

Hi all,

I was trying to work with USRP N210, but unfortunately GRC shows no USRP
device detected. But when I type uhd_find_devices; my USRP is shown. I
use version 3.3. Can anyone advise me what to do?

Best Regards,

You will need to install gnuradio from the master branch:
