VoodooI2C Help and Support

[Krennn]

Hello. Please help correct the errors that appear when I apply (patch labelled I2C Controllers [SKL])

Maybe you do not need SKL. Is your device already GPIO pinned?

I watched. Here is a screenshot of IOREG

Thank you so much for the pointers! I re-read the GPIO pinning guide more slowly and was able to successfully complete all the steps. I'm on Sierra 10.12..6

My I2C ELAN1000 trackpad works on VoodooI2C v2.0.1 with VoodooI2CELAN.

My specs are just the same as yours, I made the proper changes and applied the patches to the DSDT.dsl - except Windows 10 since DSDT was already patched with @RehabMan's Windows 8 patch for battery and USB. I'm on VoodooI2C v2.0.1 and High Sierra 10.13.3
I checked and checked again.

But I have this result:






I am attaching the proper files for you to help me out. Thanks in advance.

Krennn, GPIO Pinning start with determine your device's ACPI ID in Windows. Do you have this ACPI ID?

I do not have WINDOWS. It is possible or not to bypass this

To help it is important to know what trackpad was installed. Any Live Linux can help to find this out. This picture is made on http://www.system-rescue-cd.org/.

@Krennn - i wrote a step by step guide how to EASILY create a Linux Live USB using Ubuntu which can sometimes be handy as @anonymous-writer suggests:

See third paragraph on post #9 here: https://www.tonymacx86.com/threads/...rossing-dark-side-or-not.243618/#post-1688070. (ignore that it says it's for codec dump, in my case that's why I was creating bootable USB but the same steps will work for you)

On some Laptops the Bios IOInterruptSpecifiers is wrong.
See my ASUS Zenbook XU330UAK. It shows there 6D.
This results in 0x55.
With 0x55 I get Trackpad Settings but it does not work.
Then I test different numbers. At the end it was 0x51.
This number give me trackpad settings and working trackpad very harmonious and
multi gesture.

Thank you anonymous-writer for this hint! I tried 2 weeks without success on my ASUS UX410UQK, it has device ETPD and Pin 6D. With 0x55 i got trackpad settings but it don't work too. With 0x17 my trackpad works now!

Already mentioned in the FAQ if you look closely.
Quoting from the FAQ :-

Note that (in very rare cases), the corresponding GPIO hexadecimal pin will not work. In this case, you can try some of the common values such as 0x17, 0x1B, 0x34 and 0x55.
