Hello everyone

 

I successfully installed OS X Yosemite on my Acer Aspire V3-471G. Everything such as brightness, battery, graphic qe/qi etc. are working but the problem is one of my 3 USB Port(2xUSB2,1xUSB3) is not working. The not working port is USB2.post-1384836-1408841598245_thumb.jpg

In the picture, I put my flash drive in that hi-lighted port but nothing happened. Please help!!!

@ HBP112358   ...Thank You for this posting.   I had tried many things on my Sabertooth X79 Mobo...and nothing worked until your posting.   Now, with the kext you posted, I have my USB 2.0 ports back and working again....on Yosemite.   (Where I can use USB Mouse and Keyboard again off the back of the Mobo...(ports that are designated for the Mouse/Keyboard)). 

 

Strangely enough, though, ...the USB 3 ports still do not work...(but that's not a problem for me).   But, I was under the impression, that the purpose of GenericUSBXHCI.kext...was to add the USB 3 support....but apparently doesn't work for the Sabertooth X79 Mobo.

 

Thank you very much!
