I didn't managed TB3 hot-lug unfortunately, as far as my knowledge goes, it can't be done. I did managed trackpad already s for ow for me verythnk I need is working as it should.

Greetings

Now after transferring OC to SSD get KP...

Below 2 ioreg files. with kext version 2.4.2 where i have double-click instead of one-click. Second one is 2.2, worked on clover with added voodooInput, but this time, touchpad somehow is working properly... I don't know what is going on...will try to restart and check how it is going after restart. I also noticed that I have some ACPI errors during boot, something with GPRW method... I dont know it is much important or not...

I2C 2.2 clover.ioreg I2C 2.4.2.ioreg

I included it separately and touchpad is visible but not working. I recorded slow motion startup. There is something about voodogpio. You can see it on the photo below. Will post ioreg file in the moment

OK, with old kexts I get "Kexts\VoodooI2C.kext\Contents\PlugIns\VoodooInput.kext\Contents\Info.plist is missing for kext VoodooI2C.kext/Contents/PlugIns/VoodooInput.kext ()". I fixed that, and touchpad is visible in system, but not working at all... Logs not shows what is going on... By the way, that sineteck kext what you gave me for Realtek 525 card reader also not work, but it's not so important  

After testing a last config file from you (wasn't working also) I made some changes for paths, then i get problem with voodooPS2Mouse and VoodooPS2Touchopad. I disabled two of them and succesfull booted to system and discovered that touchpad is working and visible in system. Success... almost. when I touch the surface once, system recognize it as a double-touch (and double-click). I checked system prefs and if I disable Touch for click option then I'm disabling it totally. Any ideas?

Hi @Jake Lo,

Thanks for your effort for helping me. Unfortunately, your config not booting. Again halting on critical error, about VooDooGPI0.kext. I attached log.opencore-2020-08-08-063733.txt.zip

P.S.
I still have Clover on my SSD to start. For trying OC I"m always using USB Stick with Catalina installation. 

Hi @Jake Lo, any ideas about my trackpad? I'm stocked with that... ;(

Sure, here they are below.

config and IOREG.zip

Done. Unfortunately that not resolve touchpad problem. 

Below IOReg file.

MacBook Pro (Mati).ioreg

Yes, I added your SSDT. Kexts are up to date, baterry status working. To be honest. everything is working except this touchpad and card reader (not supported). I'm able to boot up system,  and trackpad working as a mouse, not detected in system.

I was able to boot with my config, using your TDPX file disabling my existing patches , but trackpad working as a mouse. Below picture attached.

Unfortunately that not helped.

@Jake Lo

Good morning. with your config I'm no able to boot. OC gives some "critical error" straight after choosing SSD with Catalina. Below photos of errors. Those regard kexts. I tried several versions, including newest one. no luck unfortunately... :-( I tried to disable VooDooGPIO, then I get error with VooDooI2C.

@Jake Lo HI, did you have by any chance time to look at my files?

Hi Jake Lo, below you'll find attached full Clover and OC folder. Thankd a lot for your help.

Hello folks. 
I have an Lattitude 7400 (successor of 7490) and I'm facing also same problem with making trackpad working under OC. Currently I'm using Clover, as everything working perfect,  I was trying to switch to OC, and it was almost success. The only thing not working was trackpad. Tried many guides but with no luck. sadly, I'm not so advanced in programming, but tried my best. Maybe someone will find a solution for that.  Fingers crossed.

I attached my dsdt file. I know its like looking for a needle in a haystack. but maybe you'll be able to find something together with my refi folder from couple posts above. Just let me know that you found something or not. Thanks in advance  

DSDT.aml.zip

with proper skip and count also nothing work. btw, skip and count was the first thing when I convert from Clover to OC. I have no idea where else to look ;(  Maybe in some other files is a mistake which have influence on touchpad...  I don't know. Now system is not booting with I2C Kexts in config, when they are disabled system is up and running

As you see, with your plist file XSTA rename is in wrong place, and XCRS even cannot be finded in whole file.  I also tried many versions of I2C kexts, and no luck at all I'm fighting with that soo long. and don't know even where to look for help. I tried also genI2C and also no luck. It has to be some mistake somewhere. I'm not able to find it yet...

Below you'll find dsdt after my renames. 
With your renames will post after restart in next message  

already done, same result. My skip and count should be correct as I checked last time in maciASL. now I see that even with my config system is not booting and gives me same message... wtf jus happened...

With your config I get an error :Kexts\VoodooI2C.kext\Contents\PlugIns\VoodooGPIO.kext\Contents\Plugins\VoodooGPI0 is missing for kext VoodooI2C.kext/Contents/PlugIns/VoodooGPIO.kext. Halt on critical error"

Count and skip is correct, Checked twice  I will try this config and report shortly
