Do you have a simple example at hand? I used the Prologix adapter in
the past with KE5FX toolbox but never with pyvisa. I prefer to use
Python as I want more data processing options than available with the
kit.

Python + prologix adapter is about as simple, portable, and
dependency free as it gets.
Open the port with the python "serial" library, and send direct
GPIB commands to it.
No need to install any drivers or i/o libraries, basically just
plug and play!

I do the same with my own Prologix-clone
