When I run it in USRP1 nodes, I don't get the error as before, that says it cannot find USRP1.
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.

But the benchmark_tx program says "Failed to tune to center frequency". I then tried to send it in 2 MHZ and also in 2 GHZ frequency, but it still doesn't work.

What daughtercard are you using?

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