About This File
This is the updated USB 3.0 kernel extension from Zenith.
It works flawlessly on my Acer Aspire V3-571G adding "-gux_defer_usb2" to my org.chameleon.Boot.plist kernel flags, if I don't then I get the instant wake from sleep bug.
This can be used on the Intel Panther Point H77 chipset and most other intel based laptops with USB 3.0
Download & install with a .kext installer of your choice and good luck! For more information on this .kext please see the source link.
