0X1218 works as a Trackpad but has point moving problems #4

Thank you for your efforts!

I'm using the Latitude 5290 2-in-1 and the touchpad ID is Alps 044E 1218. The touch screen worked as a trackpad, and the touchpad recognized as a 2-point scrollable mouse.

With your source code of your last release (1.3 version), I modifed value that is '#define HID_PRODUCT_ID_T4_USB 0X1216' to '0X1218' and the touchpad has been started works as a trackpad. (VoodooI2C.kext, VoodooI2CHID.kext, AlpsT4USB is in /L/E) But the mouse point was so fast that it seemed to be random movement (I think I was caught in polling mode)

Do you have any ideas for solving this?

If you need more information, here is my efi. https://github.com/laelsirus/Dell-Latitude-5290-2-in-1-CLOVER

Thanks.

Really couldn't say what is happening without seeing your ioreg & kextstat output. Also, be aware that if you are building from the latest source, this kext has transitioned to using VoodooInput so you will need that loaded as well.

Thank you for your reply. I tried both the last commit version and the last release version. I knew that VoodooInput was included in the last commit source, and I added the source and built it. The results were the same. I am currently trying with the last release version.

Here are the data before and after using the AlpsT4USB. (IOREG, Kextstat)

There is no need to use the Alps USB kext, your touchpad device supports the Windows precision touchpad protocol which is already baked into VoodooI2CHID. The Alps kext utilizes a vendor defined protocol which does not work with your device. Add the USB transport to the VoodooI2CHID info.plist and you should get a working touchpad.
