El capitan USB issues - possible fix.

[RehabMan]

Hmm I don't have an XWAK, I do have an SWAK.. This the same thing?

Method (SWAK, 1, NotSerialized)
{
Store (Zero, SLPS)
Store (Zero, PS1E)
If (RTCS) {}
Else
{
Notify (PWRB, 0x02)
}
}

Not the same thing.

Awesome - this fixed my USB 3.0 on my GA-Z97X-UD7 TH - everything is now working as expected on my El Capitan hack! Thanks much!

Would you post a screenshot of your System Report/USB?

I would appreciate any help.

I have 1 X USB 3.0 on front of my case and this is working. My GA-Z87-HD3 has 4 X USB 3.0 on the board and these do not appear to work correctly. I plugged an external USB 3 drive into the front USB 3 and it is recognised, when I plug same drive into rear USB 3 it is not recognised, however, USB 2 devices (keyboard mouse, camera) plugged into these do work.

I followed the instructions of OP carefully and did not encounter any errors while applying the fixes but I still have the same issue. Is anyone able to help me get this sorted?

Then you need the patch for _OSI -> XOSI from the BRIX config.plist: https://github.com/RehabMan/Gigabyte-BRIX-s-DSDT-Patch (config.plist/ACPI/DSDT/Patches, first entry).

Basically in Clover Configurator you need to open your config.plist and under the ACPI section you need to add a DSDT Patch.
1. click the little + icon on the right
2. for comment put change _OSI to XOSI
3. for find* [HEX] put 5F4F5349
4. for Replace* [HEX] put 584F5349

I just re read the instructions, and I'm not sure I've done this correctly. I entered the values in Clover, but I'm not sure what I'm doing re the patch mentioned in the link. Can someone give me an idiots guide to that bit?

Edit: I think I did do it correctly, entering the values in Clover under ACPI section puts the code into my config.plist I see that now, but still not working

My MB is GA-Z97X-UD7 TH
In the specifications, there is :
Chipset:
4 x USB 3.0/2.0 ports (2 ports on the back panel, 2 ports available through the internal USB header)
6 x USB 2.0/1.1 ports available through the internal USB headers
Chipset + Renesas® uPD720210 USB 3.0 Hub:
4 x USB 3.0/2.0 ports on the back panel

Although the USB is working, it is not showing as USB 3.0 on the System Report. I am not sure about which directions to follow.

Which directions did you follow?

First post worked for me

This approach (the directions in the first post) works on my setup, Gigabyte Z97N-Gaming 5, all of the USB3 ports (front and back) are reporting "Speed:Up to 5 Gb/sec".

Thanks for for your hard work.

Would you post a screenshot of your System Report/USB?

What specifically would you like to see? I have a USB 3.0 Flash Drive that shows up under the USB 3.0 Bus with a speed of "Up to 5 Gb/sec" whereas it shows up as "Up to 480 Mb/sec" when in a USB 2.0 port.

Not the same thing.

So if there is no XWAK then there is no hope? Someone else suggested it might help my sound issue but I believe XWAK is a method for the USB controller so might be pointless eh?

Thanks. Strange that it didn't work for me.
