As far as I know, there is no way to sync contacts/calendar over-the-wire (USB) using Android. That's a major ding if one is trying to avoid all things cloud.

(edit: i should add i'm referring to macos)

If the goal is just to avoid using Google, you don't necessarily need to sync contacts and calendars over USB.

You can use CalDav and CardDav with a non-Google online service like Fastmail.
