Wow. First of all I commend you for those efforts. That is great.
My first thought is that the raccoon is eating other stuff. They are naturally nocturnal. I wouldn't be surprised if he's eating at night and the only thing that is appetizing enough for him to eat during the day is live food. (kind of like I don't get out of bed at 2am for anything.... well except left over thanksgiving turkey)
I would just give it a few more days. He'll learn to eat what you are feeding.
