First of all bundle of thanks. Last post did help me alot.

 I installed a fresh gnruadio 3.4.0. Connected the USRP1 and usrp_probe ran successfully. 

Both the boards were detected. :)

When I tried to connect DBSRX2 to RXB or RXA the it wasn't detected. I mean when I ran usrp_probe the model shown was 'unkown' and frequency range was from -9000000.0 to 9.000000. Any help what I need to do in order to check the DBSRX2 ?

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 :-)

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

I downloaded UHD from link above, then I did following.

cd UHD.

cd host

mkdir build

cd build

cmake ../

make 

make install

ldconfig

But then when I ran uhd_find_devices I got following output:

"Ignoring discovered device RuntimeError: Expected protocol compatibility number 9, but got 7: The firware build is not compatible with the host code build. 

No UHD Devices Found"

Lights D and F are on the N210. No other lights.

Another question what is minimum speed required for LAN(Etherenet) interface on PC ? 100Mbps or 1000Mbps ?
