The dependencies go like this:

A: B    means A depends on B

gnuradio-core: libcppunit fftw python boost

usrp: libusb

gr-usrp: usrp gnuradio-core

Thus,

usrp is independent of any part of gnuradio.
gr-usrp is the glue that ties usrp into gnuradio.

fusb is an (essential) implementation detail of usrp.

The top-level C++ access to usrp is via usrp_standard.h

>From GNU Radio, it is accessed by way of gr-usrp which provides
usrp.source_c and usrp.sink_c
