Ball tossed off own backboard (not a shot)

[Mendy Trent]

NFHS Case Play 9.5 clearly spells out that a pass off the opponents backboard is a dribble.

It also spells out that it is NOT a dribble to toss it off your own backboard.

However, it doesn't specify what tossing the ball off your own backboard (when it is NOT a try) does once a player has ended a dribble.

For instance, is it like bouncing it off another player and you are free and clear to dribble again?

Or is it "nothing" (as if it never happened) so that a player would commit a double-dribble violation if he/she bounced the ball to the floor again?
