I find that the usrp2 could be found when I run wireshark. I searched
this question and found a thread talking about that maybe the broadcast
and multi-cast function of my ethernet card are closed by default, when
wireshark is running it opens them(they say it is under the promiscuous
mode) so usrp2 could be detected and ran files like usrp2_fft.py
successfully.
I am out of lab for now but I will return 2 days later and test the
ethernet card.
Thank you for your quick reply and happy new year in advance:)
