detector.chip.id raise AttributeError() # Avoid infinite recursion on RPI 3 B

Hi, I have an AttributeError() trying to detect my chip id (RPI 3B)

$ pip list |grep -i adafruit

Same problem with a RPI 4B also running HAOSS (Home assistant).

Interesting. Not much has changed with Blinka/PlatformDetect in a while. I wonder if this is something that is showing up in newer Python versions.

Unfortunately I'm having the same issue, RPI 5, I am running the library through docker though.

I am running the library through docker though.

Hmm, ok. Maybe that's why I haven't seen the issue before. Thank you.

I am having same problem, but I'm just blindly copying code from another codebase and trying to get it to work with my new hardware.

I would appreciate it if someone could spell out for idiots, what are the typical causes for this recursion problem?
