Hi All,
After changing my motherboard a couple months ago to an Asus Z77-I Deluxe, I have some weird USB3 issues. I have everything else working 100%, however, this is the last little niggling issue I am trying to squash. I have tried setting my BIOS to xHCI handoff to Smart Auto, Auto, Enabled, Disabled, it makes no difference.
With no kexts at all, the front USB ports do not work (which are plugged into the USB 3 header on the motherboard). I see one entry for a USB Super Speed bus in the System Profiler, which is serviced by the Apple kext.
With the latest GenericUSB kext (RehabMan), I am able to use the USB3 ports on the front panel IF and ONLY IF I have something plugged into one of them on boot up. I use my iPhone for this most of the time. Once the system is booted, I can plug/unplug anything and even get the faster USB3 speeds and the ports work 100%. Upon reboot, if I do not have anything plugged in when OS X is loading initially, the ports are dead. There is, however, 2 additional entries in system profiler for USB Super Speed Bus with the kext under either state.
Anyone else have any of these issues? Any solution?
