Fon,

You should go ahead and update your versions of uhd and gnuradio per:

http://ettus-apps.sourcerepo.com/redmine/ettus/projects/usrpe1xx/wiki/FAQ#How-can-I-build-UHD-and-GNU-Radio-from-source

You'll also need to update the boot files:

http://ettus-apps.sourcerepo.com/redmine/ettus/projects/usrpe1xx/wiki/Updating_E1XX_Boot_Files_and_Kernel_Modules

And finally, you'll need the tarball of the latest fpga files and should 
update them in /usr/share/uhd/images
