So I take a look, flip it back to the original orientation and wouldn't you know it, Goes in fine when earlier in the same orientation it wouldn't.

This tells me that prior to observation the usb plug is both right side up and upside down at the same time. Only after direct observation does the quantum superposition become decoherant and it falls back to a classical state.

That's quantum mechanics interacting with every day life on a large scale object despite the presence of gravity.
