The Canaries, though, will feel they could have recorded a first win under Hughton after taking the lead on 11 minutes through Simeon Jackson.
However, the home side's momentum was halted in its tracks on 20 minutes when referee Mark Clattenburg pointed to the penalty spot after debutant Sebastien Bassong tackled Djibril Cisse from behind, the QPR striker collapsing to the floor.
Keeper John Ruddy pushed Cisse's lacklustre effort onto the post, but Bobby Zamora was first to the rebound, slotting into the far corner.
Replays, however, showed the former England striker was one of several players encroaching as the ball was struck.
Hughton said: "I am really disappointed for the players because we had a really good reaction from last week.
"It was a game we should have won, we had the better chances and threatened more, and it was a really soft penalty which denied us the opportunity. It was a real disappointment having scored so early and having all the momentum, then conceding where you feel it was a little unjust, on two counts.
"Apart from the soft penalty, when it is taken, Bobby Zamora is at least three yards in the box when the ball is struck, and also on the same side as the referee.
"He has a tough job, to make a split second decision as it occurs, and you either get it right or wrong."
