Z68 Extreme 4 Gen 3 Rear USB 3 Ports Not Working

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi,
I've recently bought a new USB3 device but when I plugged it into the rear USB3 sockets on my Z68 board, nothing happened.  I've tried the 0.97 WHQL and 0.118 beta drivers from the ASRock support site, as well as the 0.119 version on the ETRON website.  Nothing seems to work and I get no problems reported in device manager.  The front ports work fine, but the rear ones dont appear to do anything.  If I reboot the PC with something attached to the USB3 rear ports, I get a 'device enumeration error'.  If nothing is connected, no error and no error when attaching a new device either.

Anyone any ideas whats wrong?

Thanks
Matt

	Which BIOS version do you have? Did you try to reset BIOS settings/clear CMOS?
