I think we don't understand each other :>. DSDT(eddited :>), SMBIOS, boot flags are responsible for booting Mac OS X on PC:>. USB 3.0 conected to expresscard extension slot (It's not native Lenovo usb) works great under Mavericks, Yosemite and El Captain (using genericxhciusb.kext). In Clover Bootloader USB 3.0 devices (Keyboard, HDD) are not working. Only in Clover Menu the USB 3.0 not works, in OSX and Win it's working. 

 

PS:I will try everything to get USB 3.0 to work. Also sorry for bold but i want you to know what i mean :>

I did use that firmware update in past. But still you sugest me to try another kext :>. Not working usb 3.0 (i think:>) it's not a kext thing, becuse kext is loading and working great but only when i start booting Mac OS X(SO USB 3.0 works in OSX, and kext is loading). My problem is the USB controller isn't working in bootloader, not in osx in bootloader (Clover) :>.
