This is all well for functions found in usrp.py, but even though I import usrp.py, and usrp.py successfully imports usrp1.py, I'm unable to successfully call functions from usrp1.py (i.e. read_aux_adc()). Calling the function with either a usrp- or usrp1- prefix gives me an error of the module not having a read_aux_adc attribute.

Don't do it that way ;)

Just install gr-usrp as usual, then write your test script someplace
else.  To import the usrp code, do like all of the examples:

  from gnuradio import usrp

  u = usrp.source_c (...)

You may want to take a look at the code in gnuradio-examples/python/usrp
