No USRPs found on interface eth0

Dear All,

I will ask you very old and classical question:
‘RuntimeError: No USRPs found on interface eth0’

I have USRP N200

I run:
$ sudo ifconfig eth0
$ uhd_find_devices
linux; GNU C++ version 4.4.1; Boost_103800;

– UHD Device 0

Device Address:
type: usrp2
serial: F3F0D3
$ sudo find_usrps
No USRP2 found.
$ sudo --interface=eth0 --freq=2.412e9 --interp=5
–payload=“some arbitrary text as MSDU ASCII payload” --regime=1
Traceback (most recent call last):
File “/usr/local/bin/”, line 171, in
File “/usr/local/bin/”, line 153, in main
tb = my_top_block(options, my_msg)
File “/usr/local/bin/”, line 59, in init
File “/usr/local/bin/”, line 72, in _setup_usrp_sink
self.u = usrp2.sink_32fc(self._interface, self._mac_addr)
File “/usr/lib/python2.6/dist-packages/gnuradio/”, line 1102,
in sink_32fc
return _usrp2.sink_32fc(*args, **kwargs)
RuntimeError: No USRPs found on interface eth0

Can you please help me to find a solution to this problem?

The solution is the USRP2 interface is no longer supported, and software
which uses it must be ported to UHD. The find_usrps tool is no longer
usable with modern Ettus hardware.
