I guess GRC needs root permission to execute the flow graph with USRP2.

1) run gnuradio-compandion with sudo

3) set permissions on the socket opener:
sudo chown root.root /bin/usrp2_socket_opener
sudo chmod 4755 /bin/u
Hi
I am using USRP2 with Ubuntu 10.04 and latest version of GRC.
When I run command sudo usrp2_fft.py I am able to see the spectrum (without
sudo I got error).
But when I used USRP2 source block, I am finding the error "USRP not Found".
Please guide me in this regard.

To elaborate more on my issue... I see the USRP2 send mac pause frames, and
then no new data is sent over the interface for 5-10 seconds.
