[Discuss-gnuradio] Trouble in running usrp_siggen.py (or usrp_siggen_gui

Good evening,

Currently, I am testing usrp_siggen.py (or gui version) with usrp_fft.py and usrp_oscope.py
But I have a unfamiliar error message which I have never faced.

When running siggen without SU permission:
socket(PF_PACKET, SOCK_RAW, htons(0xBEEF)): Op
eth0: socket: No such file or directory

With SU permission,
eth0: SIOCGIFINDEX: No such device

The weird thing is I have connected USRP "1" not other version which uses Ethernet port.
Thus, even though that error occurs, in my expectation, USB port works fine, and I could see something on fft or oscope.

But, in reality, i could not see anything transmitted.

I googled for those errors, and found some solutions,
1. check usrp group, and user account is a member of group
2. usrp2_socket_opener permission is set fine (sudo chmod +s (path)/usrp2_socket_opener)
3. give --usrp options to siggen (--usrp=usrp1)

but none of them solves this problem.
Please, someone give me an adivce.

Thank you in advance.
