A Beginner's Guide to Creating a Custom USB SSDT

[OwerSun]

Thank you again for your support. It is much appreciated

Thank you for your hint what needed to be added. Compilation is easy, without the hint what's actually missing I did not have any idea why it doesn't work and was using only three ports that were working.

Update - June 2019 No.2

With the USBInjectAll.kext now being actively updated again (see above and original guide at post #1) we can now move forward even with the latest hardware and system-definitions. With luck and a following wind this should take us through the changeover to macOS Catalina later this year.

Going forward we are hoping to bring out a completely new Beginner's Guide that encompasses Apple's forthcoming radical changes to how kernel-extensions are implemented. More news will follow in due course.

Big thanks to moderator @Sniki for picking up the baton, and putting in the time and effort to get the show back on the road

Good news

You won't need to worry about an SSDT for the ASMedia USB ports as USBInjectAll only operates on the main Intel ports. They do not count in the 15-port limit.

One last question please ... has remained outside the XHCI controller EH02 port PR01 and port PR12. What is it referring to? Do I have to leave everything like this, or is it not necessary and can it be excluded? Could it refer to the integrated WIFI + Bluetooth card?
Thank you.

Hi there.

So, I'm guessing you used Hackintool?

Hi there.

Yes I tried but I didn't understand how to use it. Could you help me?

I am not the developer of Hackintool. This thread is not a tutorial for that method. You should start a new thread explaining your problem and hope the developer can help.

However, looking at your SSDT_UIAC.aml ...

1) The target we are looking for is 15 USB ports.

2) In your SSDT you have 15+2

3) I do not know why Hackintool puts the 2x USB2 ports on EH02. (Also, where is EH01 ?) To do this usually requires FakePCIID_XHCIMux.kext to be installed. Perhaps you have done this.

4) Ports that are usually on the "PR" section of the IORegistryExplorer tree do not figure in the 15-limit. Because of this they are not fully configurable, so moving them to EHC is a trick to get around this. It might also be a separate "hub". The XHC controller of your Intel Z390 chipset actually has many more than 15 ports, but it is not recommended to go beyond the 15-limit, however some people disagree with this. This could be why Hackintool offers more.

I was stuck using USBInjectAll.kext full-time until this Guide put the pieces together and I finally understood how to create a working USB-SSDT. And @Sniki's new kext means I'll be able to keep following this Guide in the future (notwithstanding the big changes in store with Catalina). Big thanks to both of you (@UtterDisbelief and @Sniki)!

Hello, I have a question: If my laptop already has 15 usb ports (without custom ssdt) do still I have to do a custom usb ssdt?

Thanks to this super easy guide @UtterDisbelief

Hi! I am attempting to follow the guide but I am noticing that my internal USB as well as my Front Panel USB ports are not being recognized at all in IO Registry Explorer. I am not sure how to get these ports to show up. I have used the USBInjectAll kext, FakePCIID kext, & FakePCIID_XHCIMux kext but I cannot get my front and internal ports to show up. Can anyone assist?

My set up is i7-4790K, Asus Z97-K, MSI GTX 1060 6GB
