MacBook Pro13 FireWire port not detected

My MacBook Pro 13 inches, early 2011 can't detect its firewire port. I installed 10.12, I updated nothing. I start with 10.11 too.

When I plug my external hard drive its orange light tune one but no more. So there is some connection with the motherboard.

Curiously the SMC and Rom are not the good one's Its is for the MacBook Pro 15 inches.

It's a driver issue, a hardware or some thing in between?
