How many different devices have you tested on that port?

I had this same issue with my h115i not working. To fix i found a short normal USB cable and ran it through to the back of my chassis to plug into one of the i/o usbs. looks pretty good too.
I havnt tried anything on that usb header though so not sure if its faulty. Had the board for a year now and it hasnt bothered me.

The reason why this doesn't work is that this port only supports one USB port. Like if you plug this port into a dual USB header on a case, only one port will work. So it happens to be that the cord that the h110i comes with uses the pinout that the USB15 doesnt use. You will have to use the USB1112 for this to work. So you will be giving up one USB port by doing this. Here is the pin layout.
