[Discuss-gnuradio] Error using block UHD AMsg Source

Hi All,

I'm checking the functionality of the block "UHD AMsg Source" using the USRP N210. The device is correctly detected as you can see:

linux; GNU C++ version 4.6.1; Boost_104601; UHD_003.004.003-221-g9d6f9492

-- UHD Device 0
Device Address:
    type: usrp2
    serial: E0R17TCUP

I've attached a screen-shot of the GRC file. When I run the flow graph, I get the following error:

Traceback (most recent call last):
  File "/home/asrpuser/Desktop/Jose Torres Material /top_block.py", line 54, in <module>
    tb = top_block()
  File "/home/asrpuser/Desktop/Jose Torres Material /top_block.py", line 33, in __init__
    self.extras_uhd_amsg_source_0 = gr_extras.uhd_amsg_source(device_addr="add=")
  File "/usr/local/lib/python2.7/dist-packages/gnuradio/extras/extras_swig.py", line 5384, in make
    return _extras_swig.uhd_amsg_source_make(*args, **kwargs)
TypeError: in method 'uhd_amsg_source_make', argument 1 of type 'uhd::device_addr_t const &'

Anyone has seen an error like this before?, How can  I solve/workaround this error?

Thanks a lot for your help,
