Not working with multiple camera of the same model (2)

[michaelbaisch]

Describe the bug Can't control 2 cameras of the same model. They work individually but when both are attached the controls on both cameras control only a single camera. Similar to #47.

Additional context

I did a bit of digging and the problem seems to be the getIOService() method, for both cameras the same number is returned. I looked into the properties from IORegistryEntryCreateCFProperties of both cameras, here is the diff:

Is there any chance one of those could be used in the lookup?
