That's a problem with debug_dbs.py, not the board.  Off the top of my
head, I don't recall what's wrong, but once it's converted to use the
new transparent daughterboard handling scheme, it'll work in both

I expect to have the next version of the daughterboard s/w scheme
checked in a day or so.  It's getting even easier to use.  I've also
been overhauling the examples so that they use the new scheme and not
some mish-mash of 3 different schemes.

usrp_fpga_rev2_2005_07_30 is still good.

You may want to try using usrp_fft.py.  I believe that the version
that's checked in will handle the dbs_rx in either slot.
