See the uhd single usrp source and sink blocks in gr-uhd component of 
the next branch: 
http://gnuradio.org/cgit/gnuradio.git/tree/gr-uhd/lib/uhd_single_usrp_source.h?h=next

I believe that the benchmark rx and tx applications use a wrapper called 
generic-usrp that wrap the functionalities of usrp1 and usrp2 under a 
common API in python. So you can modify generic-usrp to use UHD single 
usrp or replace instances of generic usrp with called to UHD single usrp.
