Well that's half right, the rear usb ports are working. the front ports are not. Is this a failed MB or am I missing something. And just to be clear, I tried to plug 2 different USB 3.0 devices into the onboard plug on the mother board. The supplied USB 3.0 extension that came with My Z87 classified and an NZXT Aperture M and neither work when I plug something into the ports. I spoke to EVGA tech support a month or 2 ago and they want me to reinstall Windows. Forgive me but I'm not going to completely wipe my pc and spend countless hours installing everything back onto it to verify these ports work. There has to be another way to figure this out.
