My TouchPad (Alps Electric) is working finally. I remove the all vooddo*.kexts added before and only left the attached one. Thank you so much for your great support. VoodooPS2Controller.kext.zip

Those kexts have been removed from the EFI/Clover/kests/other, The touchpad is still not working. What can I do the next? Thank you so much for your suggestion.

Hope this EFI can get your laptop to support installing the Catalina. EFI_5400.rar

The touchpad did not working after I uninstall the USB WLAN driver. I have another try, after the installation completed without the USB WLAN driver installed, I reboot or sleep the laptop, the touchpad stop working. I have no idea how to solve that. Thank you for your suggestion.

Hi, Support I have a trackpad issue on Latitude 5400. The trackpad is not working during the installation but work well after that. And then stop working after I install the USB WLAN driver. Would you please help provide some suggestion to solve this issue? Thank you so much! Attach the EFI and USB WLAN driver for your reference. By the way, I have try to copy VoodooI2C.kext and VoodooI2CHID.kext to /L*/E* and rebuild the cache. It's not working for my issue. EFI_5400.rar TL-WN725N_V3_191229_Mac 10.15.zip
