macOS Native CPU/IGPU Power Management

Now I can only boot when I have the nullcpu kext loaded
Boot problems are off topic. Native macOS boots without "nullcpu kext." Suggest a clean install or post to the appropriate Desktop Forum
 
I have different Settings now than in Post 1016.
 
CPU PM is working

Not an audio problem
Configuration problem specific to your system, likely, USB

Yes I know that already, I have mentioned it twice in my posts.

Do you have any idea what might be causing USB usage to spike my CPU speeds?
I have a similar motherboard to yours.
 
Never experienced the problem, no suggestions.
Would you be so kind to share your config.plist with me? (Via pm if you don't want it publically available)

I just want to compare what you have against mine, since we share almost similar motherboards (Maximus series), and see if I have overlooked something there that might be causing this issue?

What you have done so far to configure your USB ports. USBInjectAll.kext? An SSDT? FakePCIID and FakePCIID_XHCIMux kexts?
 
Probably not an Audio problem as such. Consider just the USB angle.

Power management seems key here.

Thanks for your suggestion, I will go ahead and make a thread.

By the way, my problem is indeed not an Audio issue, but a USB issue. This happens for all USBs when used, the audio was just an example. My webcam, my mouse or my audio interface when used cause a spike @ max speed.

For my USB ports I am using USBInjectAll with a custom SSDT, alongside with FakePCIID and FakePCIID_XHCIMux kexts. The only issue I have with usb per se, is that I cannot rename my EC0 device to EC (as described in my post here)
