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

[cesarbahia]

Hello RehabMan!
I have a problem with USB 3.0 ports; When I connect a pendriver on port 3.0 the message: USB accessory needs power. When I boot Leptop with the pemdrive plugged into the USB 3.0 port, it appears on the desktop.

I'm having the same problems as you friend, USB 3.0 does not work right. Could you help me understand how you managed to make the HD 4600 work perfectly?

Thank you very much in advance

Follow IORegistryEntry with device connected.

Follow IORegistryEntry with device connected.

Consider placing everything on XHC (no FakePCIID_XHCIMux.kext).
Consider also config.plist/Devices/USB/HighCurrent=true (higher legacy properties).

And also your USB port configuration is wrong anyway (you didn't configure EH01/EH02/HUB1/HUB2).

Please open a separate thread.
And your ioreg is corrupt.

Hi RehabMan,

AppleBusPowerControllerUSB can be assumed to also refer to AppleUSBPowerController when referring to 10.13.x or later

It seems it has changed in Mojave... I was reading your guides for both USB port limiting and also USB power injector to tune my installation of Mojave.
Thanks to your great tutorials that help to understand the all the logic, I checked there: cat /System/Library/Extensions/AppleBusPowerController.kext/Contents/Info.plist

<key>IOKitPersonalities</key>
    <dict>
        <key>AppleBusPowerController</key>
        <dict>
            <key>CFBundleIdentifier</key>
            <string>com.apple.driver.AppleBusPowerController</string>
            <key>IOClass</key>
            <string>AppleBusPowerController</string>
            <key>IOMatchCategory</key>
            <string>AppleBusPowerController</string>
            <key>IONameMatch</key>
            <string>EC</string>
            <key>IOProviderClass</key>
            <string>IOACPIPlatformDevice</string>
        </dict>
    </dict>
    <key>LSMinimumSystemVersion</key>
    <string>10.14</string>

And so I found out it is now named AppleBusPowerController in Mojave.

So I've added EC0->EC to my config.plist and made a SSDT hotpatch as below, and it does work:

DefinitionBlock ("", "SSDT", 2, "hack", "UIAC", 0x00000000)
// Port trimmed with port comments SSDT-UIAC.dsl for THINKPAD YOGA12
DefinitionBlock ("", "SSDT", 2, "hack", "UIAC", 0)
{
    Device(UIAC)
    {
        Name(_HID, "UIA00000")
        Name(RMCF, Package()
        {
     
            "AppleBusPowerController", Package()
            {
                // values from MacBookAir7,1 in /System/Library/Extensions/IOUSBHostFamily.kext/Contents/Info.plist
                "kUSBSleepPortCurrentLimit", 1600, // changed from 2100 to 1600
                "kUSBSleepPowerSupply", 1600, // changed from 2600 to 1600
                "kUSBWakePortCurrentLimit", 2100,
                "kUSBWakePowerSupply", 3200,
            },
     
            "8086_9cb1", Package()
            {

No more instant wake from USB and no more need to make static patch to the DSDT file to fix that problem.
I still have to check if I need to increase power on USB ports for wake, or not.

Thanks again.
