Now I'm trying to test a very simple TX/RX examples
I have a USRP1 and basic TX/RX board

GNUradio flow graph is like a link here
http://picasaweb.google.com/gee.songsong/Study#5539608314025540050

When I run it by pressing F6, it is terminated with an error message like
below:

Generating: "/home/songsong/Desktop/top_block.py"
Executing: "/home/songsong/Desktop/top_block.py"

usrp: failed to find usrp[0]
Traceback (most recent call last):

    tb = top_block()
  File "/home/songsong/Desktop/top_block.py", line 34, in __init__
    self.usrp_simple_sink_x_0 = grc_usrp.simple_sink_c(which=0, side="A")
  File

line 2475, in sink_c
    return _usrp_swig.sink_c(*args, **kwargs)
RuntimeError: can't open usrp

>>> Done

I really really cannot find out what am I doing wrong :(
