USRP1s didn't require any "wire format" or firmware/FPGA changes to 
support UHD, so both "classic" and "UHD" programs will work,
   with USRP1s provided that the daughtercard in use is "pre-UHD".  
Development of the "classic" branch was frozen quite some time ago, so
   any cards that are "new" won't work in anything but the UHD environment.

What daughtercard are you using?

What rev of Gnu Radio are you using?  I strongly suggest always trying 
to run with some quite current.
