Hey John
Thanks for the quick response. I am quite confident that I included mcc134 in the import statement as you can see in the first quote in my question. I simply exchanged mcc118 with mcc134 in the "from daqhats import ..." line.
I also tried the examples for mcc134 on https://github.com/mccdaq/daqhats/tree/master/examples/python/mcc134 with the same error message.
Next step is to try call sudo "daqhats_read_eeproms" and "daqhats_list_boards" to reassign the addresses.
If you have any other idea, please let me know.
Cheers,
Leo
