[Solved] USB 3.0 stopped working for me in High Sierra Upgrade

[exleung]

I just realized today that USB 3.0 totally stopped working for me somewhere in my series of High Sierra upgrades. I know USB 3.0 used to work when I was on Sierra.

Basically, any USB 3.0 device will not show up at all. I am attaching a screenshot of my L/E folder

Any help is greatly appreciated.

Thanks

Remove FakePCIID_XHCIMux and FakePCIID.kext as you don't need them.

High Sierra has a new Raise Port Limit Patch for USB 3 on Skylake/100 Series builds.

Yes, this did the trick. Thank you very much! I removed both FakePCIID_XHCIMux and FakePCIID.kext and followed the instructions to "Raise Port Limit Patch for USB 3", and it works beautifully.
