You may have a version mismatch between the installed python modules in
lib and installed python scripts in bin. Either that, or its a very old
bug. Whatever the case, I recommend you nuke your gr install(s) and grab
a recent release.

What do you want to test? If you want connectivity, install UHD and the
command uhd_usrp_probe will tell you all the USRP devices connected to
your pc: http://code.ettus.com/redmine/ettus/projects/uhd/wiki

If you want to test signal integrity, configure gnuradio with gr-uhd
support. There is a very basic signal generator and analyzer display
that comes with the component. uhd_siggen_gui.py uhd_fft.py I believe.
Or make a quick flowgraph in gnuradio-companion :-)
