ten second count starts when?

I should also point out that this is different from when the shot clock starts under NCAA rules or for those that use it in NFHS. After a made basket, the shot clock starts when the subsequent throw-in is legally touched or touches a player in bounds.
So if the throw-in pass is deflected and not immediately controlled by a player, we could have a situation where the shot clock could be running for say 3 seconds and the ten-second count hasn't even started. This means that in a men's game the shot clock could show 23 seconds remaining and a team could still be trying to cross the division line without committing a 10-second violation.
