have you read this about UHD630? https://www.firewolf.science/2018/11/coffee-lake-intel-uhd-graphics-630-on-macos-mojave-a-nearly-ultimate-solution-to-the-kernel-panic-due-to-division-by-zero-in-the-framebuffer-driver/
im not sure but i guess you can always disable the intel injection from config or clover GUI. basically you just have to try it to see what direction you need to go in.
ok i see. are you sure you are formatting the SSD properly with disk utility maybe it is not showing up in the selection menu and you are accidentally installing to the 16gb usb installer which is not enough room to install macos too?
I had a similar issue reseting the power profiles works for a bit but I ended up having to reinstall Mojave clean since I had upgraded from Sierra I guess there where bad permissions somewhere.
you can try fusing both drivers to see if it helps. use the voodoops2controller kext with the keyboard that works and swap out just the trackpad kext inside the plugins folder with the one that works.
ok if it gets stuck on waiting for root device then that is most likely caused by the USB port dying during load so try different ports. or try pulling it out and putting it back in at that point on another port.
according to https://github.com/acidanthera/AppleALC/tree/master/Resources/IDT92HD93BXX layout 12 is the correct layout id. are you sure you dont have other audio related kexts that are not the apple stock ones in maybe S/L/E or in L/E also check the clover kexts os version your booting folder. i believe also clover rev 4700 has also injection issues. if you are on that version update it to latest also
make sure to have latest lilu and applealc. some older versions of lilu had injection issues. also make sure they are in clover/kext/other folder. and that you have injection set to yes not detect in clover config.
the issue is the firmware for those models DW1510, DW1550, DW1560 probably a few others are outdated. dell has not released any new firmware's for them as they are manufacture specific even though the hardware States 2070a.
i think you can adjust speed with the trackpad prefpane if not you might have to edit the trackpad kext info.plist
also i do not believe apple uses PrtScr and Insert buttons hence why they might not be working.
