So i recently built my new PC and everything is great apart from the two USB 3 sockets on the case, no matter what i plug into them it always says usb device not recognised, the motherboard also has 4 usb 3 slots on the I/O panel and these all work perfectly, i just can't get the ones on the case to work 
here's the case and motherboard i have,
