I am attempting to run"usrp2_fft.py"
I have a USRP2 with an RFX900 card and a fresh install of Ubuntu 10.04
- the latest release of gnuradio/UHD (installed yesterday).
When I run “sudo ./usrp2_fft.py” I receive the following:
Traceback (most recent call last):

RuntimeError: No USRPs found on interface eth0
When I run “uhd_find_devices” I get:
– UHD Device 0
Device Address:
type: usrp2
addr: 192.168.10.2
name:
serial: 2587
HOWEVER, when I run “sudo find_usrps” I get:
No USRP2 found.
Is something wrong here or do I need to remove the UHD in order for
the scripts in gnuradio/usrp2/host/apps to work? None of them seem to
be able to detect my USRP2 even though I can ping it all day long and
uhd_find_devices and uhd_usrp_probe have no trouble.
