You can make reversible connectors without intelligence (adaptiveness). Just use 2x the number of contacts, in a mirrored layout.

Requires more physical space for the same number of contacts, but USB doesn't require that many contacts to begin with.

This is how the older Fitbit accomplished the task and it works just fine.
