mrphumin Posted August 24, 2014 Share Posted August 24, 2014 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. In the picture, I put my flash drive in that hi-lighted port but nothing happened. Please help!!! Link to comment Share on other sites More sharing options...

BitMangler Posted October 19, 2014 Share Posted October 19, 2014 @ 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!
