    ROG maximus IV extreme-z USB 3.0 Driver problem

    Hello.

    I have an ROG Maximus IV extreme-z MOBO (with the most updated bios version) and only 2 out of 8 +1 (On the front panel) are working...

    It seems to be a driver problem.. But I deleted and installed the usb driver countless times with no success of fixing it...

    It worked fine untill now.. I have no idea why ... Please Please help me

    Thank you.

    What Win OS are you running ... what bios version are you on ...

    Those 2 Unknown Devices should be showing as Generic USB Hubs ...
    ... have you updated your Intel ME driver, or Intel Chipset driver lately ...

    When's the last time you cleared cmos ...
