Using 8451 USB-SPI interface from Python

Is there a way to talk to the NI-8451 USB-to-SPI interface from Python using a Python package such as PyVISA ?

USB-8451 is not a VISA device and requires NI 845x drivers to control the device.


There is no official direct support for 845x in Python as per this NI article -


But, you can the 845x C dll in Python to use and looks like some folks have even shared it on Git for public use.
