uhd_usrp_probe --args "type=usrp1" You'll find that it can cope with the DBSRX2 just fine. Since you're a new user of this gear, without any necessity of backwards compatibility with older software, you should be using UHD exclusively. > > 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.

Follow the instructions here to update your N2XX firmware: http://files.ettus.com/uhd_docs/manual/html/usrp2.html#load-the-images-onto-the-on-board-flash-usrp-n-series-only If you used the "build-gnuradio" script to build your Gnu Radio + UHD installation, it will also have downloaded the very latest master firmware, and placed it in /usr/local/share/uhd/images. You might also look at the overall UHD documentation here: http://code.ettus.com/redmine/ettus/projects/uhd/wiki#Documentation -- Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org
