Light bar gets dimmer when I put it to charge

I have replaced the charger board and the ribbon cable while a whole new set of them, but I try to plug my controller in through the front USB port. The light bar gets dimmer and dosnt’t charge. I have another older controller, and it doesn’t have that issue. I also bought 2 new cables, and the original cable non of them worked. I have tried resetting the controller. It didn’t help. I tried forgetting the controller also didn’t help. I have a charger dock that uses the port at the bottom to charge, but I don’t want to put on there in the middle of a game. Will I have to get a new motherboard or replace the whole controller
