XHCI Pre-Boot Driver (Intel Z77 Chipset)

xHCI Pre-Boot Driver (Intel Z77 Chipset) Should I have this enabled or disabled. Not sure I just got this motherboard and I'm kind of playing around with settings in the bios. I have not found anything online so far.


Thanks So much!

    It says Enabled The USB 3.0 ports are routed to the xHCI controller before booting to OS. (Default)


    Then it says... Disabled The USB 3.0 ports are routed to the EHCI controller before booting to OS.

    then it says...When this item is set to Enabled, the xHCI Mode below will be automatically set to Smart Auto; when this
    item is set to Disabled, the xHCI Mode below will be automatically set to Auto.

    I'm still not sure though!
