After Yosemite update some USB ports not working

I just successfully updated my hackintosh to Yosemite form 10.9.5 to 10.10. I realised that half of my usb ports aren't woking, but they worked perfectly with Mavericks. And the ones that work change upon each reboot. Any ideas???

 

I'll bump this thread as I'm getting exactly the same problem.

To add to it, my keyboard takes about 3 minutes to get found on bootup, and it's a usb keyboard.

 

Same problem here. I've lost 2 USB ports on the front of the case.
All on mobo work fine.

Also, can't get iMessage to work.

I am having the same issue on my gigabyte Z77-DS3H after update.

 

Don't use the 'USB 3.0 Universal Kext' in MultiBeast, Yosemite comes bundled with those drivers already and you will get conflicting results (Ports not working) on your system.

 

Correct. USB 3.0 Universal is only for series 5 & 6 boards. 7, 8, & 9 do not need it.

 

How do i delete the Universal 3.0 installed with Multibeast?

 

Here is the link to the thread that talks about it and the post to remove the driver.

I personally just reinstalled yosemite cause it only takes 15min total for me.

 

Thank you!!! I just deleted it as described... Now it works just fine

 

I did this and now all of my USB 2 ports are working stably, but none of my USB 3 ports are working.
