My USB 3 ports have stopped working. They were working just fine under the beta versions.

Installed various drivers to be found around the net, but to no avail.

My system: P67 Sabertooth Asus mobo, Resneas USB 3 ports, Clover install.

Everything else is working normally.

Has anyone had a similar problem and managed to fix it?

My situation is like yours.
It was updated, not clean installed.
My USB3.0 works when I boot into installation normally from my Yosemite installation USB drive,
But when I try to have a normal boot, the USB3.0 fails.

the GenericUSBXHCI.kext doesn't work, it even makes the boot into installation from usb fail.

You guys will be surprised how much could be fixed just by running Kext Utility and let it repair the permissions after fresh install. 

 

Of course that happened automatically when I manually deleted the USB3 kext and re-installed it again using Kext Utility.

To no avail.

Try download USB3.0 signed by niresh.

I just discovered that the GenericUSBHCI.kext was loaded after all.

Deleted it once and for all, repaired all permissions and cleared all caches, and it's working now.


I spoke too soon. It worked exactly once.

Now back to not working again.

Update:
 

the situation becomes wired.
the USB ports are working in Bios, Clover boot screen.
but at once it goes into OS X, all the USB ports are unable to use for 1 minute(including USB 2.0).
after 1 minute waiting, then the USB ports are work again.

 

already deleted the GenericUSBHCI.kext, having no idea what's going on.

Hey,

 

i have the same issue as you, Usb not working fine after upgrade to Yosemite. A quick search on google learn me that many people using real mac have same kind of problem with Usb, after upgrading to Yosemite. maybe an official update from apple could solve this. But maybe i'm dreaming...

I had the same problem with GenericUSBXHCI.kext. 4 ports USB 3.0, but worked only one.

 

Tried binary patch:

 
Find: C680S800000001 
Replace: C6800000000 
Name: AppleUSBXHCI 
 
also didn't help...
 
In the end, all 4 ports 3.0 works fine with Fake ID  :)
 
<key> XHCI </ key> 
<string> 0x0c033000 </ string>

With this kext the USB3 ports at the back of my PC are working now, not the one at the front.

That will do for now though, so it's all good.

Thank you!

 

EDIT: On second boot all USB3 ports are working now, so everything working perfectly.
