The StarTech and CalDigit cards both work on my Mac booted into Windows 7 (BootCamp), so I know the cards work and work with the Mac's hardware. On Mavericks the StarTech was more reliable and I also like it because it fits flush, so I can leave it in place when putting the Mac in a carrying case/bag.

This card does work on OS X 10.10 sometimes. I also have a CalDigit USB 3.0 express card and CalDigit have provided drivers for OS X 10.10. **Some background related information as to why I think I can get this working once I can persuade OS X 10.10 to use this GenericUSBXHCI.kext. Also all this worked with Mavericks (see more details below). I have also attempted to rebuild the kext cache as explained here: kextcache -m /System/Library/Caches//Startup/Extensions.mkext /System/Library/Extensionsīut not lucky so far - plugging in USB 3.0 drive into USB 3.0 port doesn't show drive on Mac OS desktop, using othe, but USB 2.0 ports do work so drive is OK. I have set permissions of the kext and used Drive utils to repair permissions to ensure correct permissions. There is a version of the kext for Yosemite here.

#USB 3 DRIVER FOR MAC MAC OS X#
I want to install GenericUSBXHCI.kext on Mac OS X 10.10 so that I can use my StarTech Ecusb3s11 flush fitting USB 3.0 expresscard. Failed to do the driver install-failure message on screen-when I last tried last week or any other automated tool. Note that I want to try this manual approach first before using MultiBeast.
