This answer claims that both micro USB ports of the Raspberry Pi Zero can be used for OTG and that the
PWR IN connector supports data transfer. As much as I want that to be true, I can't find a single other resource supporting this claim.
To the contrary:
- these answers explain that the Pi A/B do not support OTG over the power port because data pins are unconnected; presumably the same is true for the Pi Zero?
- in this thread at the Pi Forums, user
You can't kill the Zero by plugging the power into the data USB socket. It will work fine like that. You can't use the power socket for data though.
So, is it true or false the
PWR IN port supports data transfer? Please don't respond without details and evidence to back up your answer.
I expect the answer is 'of course not' but I would love to be surprised. And, yes, I plan to fix that one answer if/when it's proven wrong.
