Hi,
I took the advice on this thread and purchased an Inatek 4 port USB PCI card for the MacPro 3.1 I'm working on - I downloaded the Generic Driver
GenericUSBXHCI
Open Source USB 3.0 xHC driver for OS X 10.7.5 - 10.9
But there's no apparent way to install it. If I simply drag the .kext file into the System Library Extension folder it tells me it's been improperly installed.
When I check the System Profiler I see the Inatek is recognized, but there is No driver installed, so, I'm assuming it isn't going to work. There is no USB 3 superbus that shows up in the USB profile, either.
Could use some help installing the .kext file - the driver, so I can use this card I've purchased. Thanks very much,
Paul
