The N210 is a UHD-only device.  You'll need a more recent version of Gnu
Radio, and you'll
  need to follow the UHD build instructions here:

http://ettus-apps.sourcerepo.com/redmine/ettus/projects/uhd/wiki

Also, find_usrps, and usrp2_fft.py are "classic" API programs--they
won't work with UHD devices.

But you can synthesize the functionality of usrp2_fft.py for UHD within
GRC pretty easily.

You can use uhd_find_devices (once you have UHD, and Gnu Radio
compatible with UHD) to find
  UHD-type devices.
