First of all in my folder I don't even have the USB.kext
And even I manually install usb3.0 universal from MultiBeast after restart using boot flag -f still could not find the USB3.0.kext
Now only some ports are woking, maybe like 1 or 2.
And with every restart the ports that worked keep changing....
Sounds like you either have a faulty motherboard or several USB3 options installed that are conflicting. Different kexts loading on different power ups. To remove the USB 3.0 - Universal option from MultiBeast Try this:

If you have a spare HDD or SSD to hand that you can do a fresh clean installation on to see how the USB ports work then it might be an interesting exercise.
