Mihari Oyama Posted July 13, 2023 Share Posted July 13, 2023 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: . This is my EFI: https://drive.google.com/file/d/1z4nqtrR6qPXd51w20Uobuuk4iaxg-hcW/view?usp=share_link All your help will be appriciated. Please help me this.

Administrators Hervé Posted July 13, 2023 Administrators Share Posted July 13, 2023 Try and add the USB HID patch in your OC config. You'll find the details of the path in my Latitude E7270 guide and/or through a forum search. Link to comment Share on other sites More sharing options...
Mihari Oyama Posted July 14, 2023 Author Share Posted July 14, 2023 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.

Mihari Oyama Posted October 24, 2023 Author Share Posted October 24, 2023 I thought it would never work. And I had sold this machine. Link to comment Share on other sites More sharing options...
