大家好。
刚刚接触GNURadio和USRP，今天在Fedora11里编译完后运行"gnuradio-examples/python/apps/
hf_explorer/"中的例程，使用的命令如下

./hfx2.py 9500k

输出如下错误：

Unable to find PowerMate or Contour Shuttle
usrp: failed to find usrp[0]
Traceback (most recent call last):
File "./hfx2.py", line 799, in <module>
app = MyApp(0)
File "/usr/lib/python2.6/site-packages/wx-2.8-gtk2-unicode/wx/
_core.py", line 7938, in __init__
self._BootstrapApp()
File "/usr/lib/python2.6/site-packages/wx-2.8-gtk2-unicode/wx/
_core.py", line 7512, in _BootstrapApp

File "./hfx2.py", line 794, in OnInit
frame = MyFrame(None, -1, "HF Explorer 2")
File "./hfx2.py", line 248, in __init__
self.src = usrp.source_s(decim_rate=options.decim)
File "/usr/lib/python2.6/site-packages/gnuradio/usrp/usrp_swig.py",
line 2059, in source_s
return _usrp_swig.source_s(*args, **kwargs)
RuntimeError: can't open usrp

====================

请问：
这个usrp模块应该怎么找到？

命令写错了，是
./hfx2.py -c 9500k

1、USRP电源插好没？
2、USB线插好没？

这个程序需要你连接usrp，它没能打开usrp，所以就报错了。

好象有个grc的例子可以不需要usrp

是这样，usrp下周才能拿到，我只是先试一下环境，不过这个python找不到模块的错误不解决接上usrp也会有这个错误呀

今天看代码了，是Runtime error，这个错误原来是swig调用C++那里报出来的错误呀。
