USB suddenly not recognizing devices

Hello,

I have a problem.

My MacBook Pro suddenly stopped recognizing usb devices. This morning everything was working fine, but for some reason a couple of hours later it's not working anymore.

I can connect my phone via usb and it's reloading the battery. I can't get into my files though, while I was able to do that this morning.

My MaKey MaKey also gets power and the lights flash. I can use it to play an online game. It isn't being recognized as an usb device though, and I can't upload new code to it.

I haven't changed anything between the point it was working and the point it is not working anymore.

The only change is that I've tried to connect my MaKey MaKey and upload code to it. But that didn't work, because it said there was nothing connected to my usb port. That's how I found out that it was broken.

I have tried resetting my PRAM and SMC but it both didn't help.
