Is there a way to force CGminer to only stick to ANU recognition?
Not really. There was hardly anything different between many many devices that used the exact same communication protocol because hardware manufacturers didn't want to think about it, used the same usb chip, and were too lazy to add a simple identifier on their usb devices. Adding more commands now for such old slow hardware is a bit of a waste of time I'm afraid.
Totally understandable! Thanks for the very quick reply CK!
Edit:
This is the error message that gets shown:

I don't expect any update or changes, I only value my U1 as a realtivly cheap tool to get my training wheels off.
