[Discuss-gnuradio] RuntimeError: No USRPs found on interface eth0

[vivek thotla]

Hello,

I am using USRP2 with a EEE PC (1015PX) which has ubuntu 11.04 on it. Since the USRP2 communicates only gigabit, I bought a Linksys SE2800 Gigabit Ethernet switch and connected the USRP2 via the Ethernet Switch (The EEE PC does not have  a gigabit ethernet card). I switched on the USRP2 and I got the D and F led lights on after all the led lights flashing. I run the usrp2_fft.py program and I got this error:

address@hidden:~# usrp2_fft.py
Traceback (most recent call last):
  File "/usr/bin/usrp2_fft.py", line 273, in <module>
    main ()
  File "/usr/bin/usrp2_fft.py", line 269, in main
    app = stdgui2.stdapp(app_top_block, "USRP2 FFT", nstatus=1)
  File "/usr/lib/python2.7/dist-packages/gnuradio/wxgui/stdgui2.py", line 36, in __init__

    self.top_block = top_block_maker (frame, self, vbox, sys.argv)
  File "/usr/bin/usrp2_fft.py", line 70, in __init__
    self.u = usrp2.source_32fc(options.interface, options.mac_addr)
  File "/usr/lib/python2.7/dist-packages/gnuradio/usrp2.py", line 679, in source_32fc
    return _usrp2.source_32fc(ifc, mac)
RuntimeError: No USRPs found on interface eth0

Then I tried to ping the usrp2 by connecting it to my laptop which has a gigabit ethernet, but I don't get any response from it. The request is timed-out everytime. I also tried all the solutions possible from the list, nothing works for me. 

Please Help.
