El capitan USB issues - possible fix.

[iadmir]

Find Method XWAK in your DSDT...

Method(XWAK, ...
{
   ..some code...
}

Change it:

Method(XWAK, ...
{
   Return(0)
   ..some code...
}

Where to find DSDT?

Thanks this guide worked for me on a Asus z97 pro wifi ac

Hi,
I got the same board and this guide has not worked for me. I had vanilla kexts, and no other mods. At the begining I had two USB3 ports working, but after multiple reboots none of them work now. I'm also flooded with the following message:

9/7/15 4:48:20.000 PM kernel[0]: 000598.797120 ASMX@00000000: AppleUSBHostController::setPowerStateGated: going to state 2 failed with 0xe00002e9
9/7/15 4:48:20.000 PM kernel[0]: 000598.797204 ASMX@00000000: AppleUSBHostController::setPowerStateGated: going to state 1 returned 0xe00002e9

Any clues?

Thanks

Did you 2xusb3 ports work correctly? Ie at usb3 speeds?

if so I spect you simply need a port injector to get them all working.

Where to find DSDT?

On the clover boot screen press F4 on your keyboard.

Boot into OS X and mount your EFI partition.

Your DSDT will be in the EFI/CLOVER/ACPI/ORIG folder.

Edit it and save it into the EFI/CLOVER/ACPI/PATCHED folder as DSDT.aml
