Shot Clock Reset

[rbruno]

NFHS game. Ball is released by Team A just before the shot clock expires. My partner as trail blows a shot clock violation just as the ball hits the rim and the horn goes off (he said he didn't see it hit the rim). I clearly see the ball hit the rim as does team A's coach on that side of the court. I blow it dead and reset the clock and give the ball to the team I thought had the ball (Team B) when the horn blew. Did we administer this correctly and would it have been different if Team A had the ball or if no one had control etc.?
