Ursp_dbid.dat question

Hi,
While trying to implement USB interface for windows I am facing a
problem.
When I try to compile my code it asks for usrp_dbid.h, and usrp_dbid.cc,
however these are generated from usrp_dbid.dat. According to my
understanding usrp_dbid.dat is loaded from daughterboards. Am I right?
How
is this loaded from daughterboards, so I can use the two files in the
compilation of my code?

gen_usrp_dbid.py
