I have a Gigabyte GA-Z87X-UD5H Z87 motherboard all of them usb ports are 3.0 but when i plug in my mouse and keyboard into the motherboard they like reset all the LEDS go out for about a second then turn back on. Sometimes the lights come back on but i have to unplug my mouse and plug it back in. So out of curiosity i tried my front 3.0 usb on the case and now my mouse is working fine i have not noticed it resetting. Side note this one and my last motherboard have need an rma for usbs not working at all including the front case ones I never found out why.
