On my device I patch USTP, 8 (Find: 55535450 08) to XSTP, 8 (Replace: 58535450 08).
Then added this via an SSDT: Name (USTP, One)

Ah! Thanks for that! I'll give it a go in the coming days. :thumbup:

Hi guys,
i need your help again to fix SYNA3602 touchpad.
Kexts are loaded correctly (VoodooI2C and HID) and VoodooGPIOSunrisePointLP is present in Ioreg under GPI0. Trackpad preferences are visibile under system preference but the pointer doesn't move.

I've done various try without any luck.. Thanks
Mattia

Hello all.

Thank you guys for fantastic piece of work - VoodooI2C.

Used it in a few of my builds but with the latest one I hit a dead end.

I got a ASUS ZenBook PRO UX580GE with ScreenPad 2.0 and Touch Screen. The Touch Screen is working with VoodooI2C without anything done for it but the ScreenPad is giving me hard time. I managed to have the VoodooI2C and VoodooI2CHID loaded for it but is seems that something is wrong with enabling it or with my GPIO pinning.

The ETPD device is reported to be GDX1515

I've follows the VoodooI2C guide and did a SSDT with GPIO pinning and also attempted to do it with the help of GenI2C app and in both chases I got the same result - Kexts are loaded but there is no response from trackpad.

I also attempted the polling method with the same result.

I've tested with the following values for GPIO pinning: 57, D7 and F7.

I also replaced _STA method in ETPD device to return 0x0F with the same result as without replacing the method (with both I get the value of _STA set to 0xf - checked it with IOReg in ETPD device).

Any help or hints are welcome.

I had the same problem with my ASUS UX434FLC. The Screenpad device did not work at all. A little detail helped to solve the problem in my case: As you can see in your ioreg the VoodooI2CTouchscreenHIDEventDriver is binding to ETPD. This is probably caused by the nature of Screenpad (it is both: Touchpad and Touchscreen). Thanks to the user zhen-zen who gave me this hint I could make my Screenpad usable:

- Find the right gpio-pin (as you already did).
- Use the latest version of VoodooI2C.kext and VoodooI2CHID.kext.
- Inside of VoodooI2CHID.kext edit the file Content/Info.plist and remove the whole section starting with "<key>VoodooI2CHIDDevice Touchscreen HID Event Driver" and also the following "<dict>" section.

This way there is no Touchscreen support inside VoodooI2CHID.kext. After this change, the "... Touchpad HID Event Driver" is now binding to ETPD. From now on the Screenpad is working for me.

A small problem remains: The clicks are not recognized properly and the multitouch is not working at all - but it is a start.

@boardschauer thank you for the hint.
I will dig into it and see if it works for my rig and if it dose I will check why needs the Touchscreen HID to be removed from the VoodooI2CHID.kext.

@boardschauer your hint worked perfectly. Now I have a working trackpad and also a working touch screen with stylus (no more finger touch response) and that is the perfect combo for me.
So once again thanks for the hint.

I am facing one issue though: The touchpad is recognizing only one finger at a time. So no gestures are recognized, e.g. scrolling with two fingers. It doesn't matter which setting I choose in the touchpad settings. With the tool FingerMgmt I see that the touchpad is recognizing only one finger. Any hints on this?

I can confirm that the same thing is happening here and also sometimes when I boot/reboot the trackpad is unresponsive (I have the driver in EFI/Clover/kexts/other).
I will dig into the code and also look in the linux driver code to see if I can find a solution.
