Dell Latitude 7390 Touchscreen Help

Recommended Posts

I have installed Ventura (13.4.1) on Latitude 7390 (not 2-in-1 version) and it worked well expected touchscreen.
I already:

- mapped USB
- tried to patch TPL1 and TPD1 device in DSDT

- used all VoodooI2C's kext relevant

but all of them only make my trackpad worked, not touchscreen.

There are images about SiW (Siliconworks) HID Touchscreen (It used USB protocol) and its IOReg:

I found that when I disabled all VoodooI2C's kext, its could touch but cannot move or 'click' mouse everywhere in screen.
And when I restarted with VoodooI2C enable, only trackpad worked.
Even though I added USB HID Patch in E7270 OC config, touchscreen still not happened.
