I'm using Enoch, not Clover since Clover never worked with my setup.
Updated from 10.11.3 to 10.11.6 with Comco Update. I backed up my /Extras and in /S/L/E the following kext´s:
"AppleGraphicsPowerManagement" ,
"AppleHDADisabler"
"VoodooHDA"
"IOUSBHostFamily"
"IOUSBFamily"
Replaced the Kernel for 10.11.6 in /S/L/Kernels with the one provided by user VoiletDragon
here .
Put the KEXT's back in place with Kext Utility and repaired permissions before booting.
All works fine ...BUT... no USB.
So obviously putting the old USB-Kext's in place was a mistake as it seems. I have USB-support only when I boot -f in Enoch.
Any ideas? I have no backups of the original 10.11.6-kext's I have replaced with the ones from my backup.
