Re: [Discuss-gnuradio] USRP2-No USRPs found on interface eth0

[Brook Lin]

Thanks, Tim. The error I got is

~/gnuradio/gnuradio-examples/python/usrp2$ sudo ./usrp2_wfm_rcv.py -e eth0
Traceback (most recent call last):
  File "./usrp2_wfm_rcv.py", line 274, in <module>

in source_32fc
    return _usrp2.source_32fc(*args, **kwargs)
RuntimeError: No USRPs found on interface eth0

The output of ifconfig |grep eth is 
"eth0      Link encap:Ethernet  HWaddr 00:17:a4:eb:e0:ee "

And I also tried what you mentioned above. However, I still had the same
error. Any advice?

Thanks,
Brook
