MCC 152 can be detected but unable to open port



SPI and I2C are both enabled. When I run the MCC DAT HAT Manager it is able to detect the MCC 152 from the List devices 



The address is correct but I am unable to open the device and write signal to the DIO and AO. 


Is there anything I am missing? I am running the latest Raspbian on Pi 4 with Python 3 installed. 

Is there anything I can check or probe on the HAT to verify it is working? 

Thank you.
