[Guide] USB power property injection for Sierra (and later)

hello @RehabMan

with the help of this guide (fake ec controller) n port injection in AppleUSBEHCIPCI.kext (6 ports)
so now the ports are loaded in EC (please have a look in ioreg in the archive)
through dsdt patches (through clover)


so please can u guide me as to which kext I should insert the power property manually (kusbportcurrent)
(as I have no plans for upgrading/updating the os in this built, hence no override issues .. please correct me if I am wrong)

thank you.

EC is a bad name choice for an EHCI controller. Recommend EH01/EH02, as that is what USBInjectAll.kext requires.

Power properties are now loaded under EC though (not the EC that is really an ECHI...).
 
Hi,

I often use USK Keys to copy things around, install OS and I noticed they get hot.
They've a metal construction, so they transfer heat quickly and effectively.
So in MacOS they get really hot, in Windows they don't.

I've implemented the USB SSDT as per RehabMan guide but I never considered the USB power at something to look after.
I've added the screenshots of 3 different devices plugged in the USB 3.0 of my Gigabyte Z370N WiFi.

I've also added the IOReg of my machine.
Are those mVolts too high? Should I look after the USB power?

Thanks for your help.

Your ioreg proves you did not follow post #1.
 
@RehabMan can I ask Mojave USB2.0 problem in here ('cause title is saying Sierra and later) or should I open the new thread on Mojave Desktop Support?

This guide applies to Mojave as well.
But it has nothing to do with USB2.

While I using it suddenly I am losing USB2.0 port connection. I have combo WIFI-BT and Bluetooth using internal USB2.0 port for connection. I am using PMHeart USB port patch with your Inject.kext. But I didn't figure it out why this happening? Can you look at my files what is going on?

I forgot I am also using SSDT.UIAC.aml.

Which device/port is losing connection?

No I did not.
In fact I asked two questions:
"Are those mVolts too high? Should I look after the USB power?"

Then if the answer is yes I go back to post 1 and implement the change.
Thanks!

This thread is not for random questions.
Expectation is that users posting here have followed post #1.
 
Which device/port is losing connection?
HS09
HS10
HS14

These 3 USB2.0 port are affecting each other. Here is what happens; On HS10 connected my iPhone charge cable. When I connect my iPhone to this port and my magic mouse BT connection lose and BT says No Hardware. I don't know how but, motherboard rear USB2.0 port is affecting internal USB2.0 port while using it somehow?
