Hi i just built a new setup using the Asus P8Z77 v-lk board. Since i have not been able to get the intel usb 3.0 ports working, the others work fine. Ive tried various drivers and cannot find a solution
interesting post over on AnandTech. May shed some light. Basically, it seems the P8Z77 board was fitted with an H67 chipset. So, the Device Manager reported "Intel 6 Series/C200 chipset family" instead of the Intel 7 Series/C216 chipset family. This is a rare event, but may not be isolated.
Check in your Device Manager under System Devices, USB, or IDE ATA sections to see if you have 7 series or 6 series controllers.http://forums.anandtech.com/showthread.php?t=2293117
