I have built my system and all the USB ports on the back of the case, coming directly from the motherboard are working perfect, even the USB 3.0 ports 
But for some reason the USB 2.0 and 3.0 are causing problems on the front of my case the USB 2.0 only work with the first controller I put into it all other controllers do not work, and the USB 3.0 ports constantly say device not recognised even though the controllers work from the USB 3.0 ports on the rear of the case.
Has anyone got any suggestions for this thanks
