Solved USB3 freeze problem at boot in Asus X301A (Intel XHCI 8086 1e31)

I wanted to share my findings. Prior to some minutes ago I couldn't have my USB3 port in the laptop working, this since Yosemite, now I am on Sierra.

My laptop would freeze at MBINIT done during boot if I left XHCI enabled in bios hence I needed to disable it and lose USB3 functionality.

Some days ago I read a thread on reddit, this guy had the freeze and solved it by selecting hand-off in bios for xhc, the problem is this laptop and bios doesn't have such an option.

After many tries with DSDT patching and bla bla today I found what the solution was.

 

It was simply a matter of selecting "FixOwnership" in Clover! WTF!!! Now the USB3 is working with the aid of that flag and FakePCIID_XHCIMux.kext .

 

So to all those people that have this problem try to put that damn flag.
