Which macOS version are you running ?
You didn't tell if Display Prefs Pane works without DisplayMergeNub.kext
Please remove:
DisplayMergeNub.kext
HoRNDIS.kext
you have to remove them until we do the usb port testing because they interfere with usb ports, also don't use google chrome until you do the testing and you send the files.
After that you can install them back.
repair permissions : Type in terminal:
sudo kextcache -i /
Wait for the process to finnish, reboot and see if it works.
Here are the new Files:
SSDT-T440.aml - add it to EFI>Clover>ACPI>Patched
DSDT.aml - add it to EFI>Clover>ACPI>Patched
config.plist > add it to EFI>Clover
Reboot & test things:
- Test if battery status is working correctly
- Test Brightness FN Buttons are working for increasing/decreasing brightness
- Does the LED stop Blinking after wake from sleep.
- Send IOREG one more time with USB test but for USB2 device use a usb mouse as it will be much easier for me to spot them and for USB3 use whatever USB3 you can grab for testing : External 3.0 HDD or USB3.0 Flash Drive. (do the ioreg thing only after you removed the horndis and displaymergenub kexts ; repaired permissions and reboot with new files " Very Important ! " for successful results)
Report back with Results and with Full "Problem Reporting files"
Good luck Friend !
