Some hardware devices do not respond to these probes, or could be in reset when software object is created. Default behavior is the same (probing occurs).

PCA9536 is one. Doesn't appear to linux's i2cdetect either.

Hi! Would you mind moving the try/except into a separate private method? It'll make the __init__ clearer that way. Please rephrase the existing comment to mention that it's only done when probe is true. Thanks!
