USB power managament on Catalina.

[mathewgx 1]

I have a problem on Catalina with usp power.

Applebuspowercontroller isn't loaded under EC.

At High Sierra it is , with the same config.

Can you help?

Send me CATALINA.zip

Since this is the only place online I'm seeing it discussed so far...

AppleBusPowerController.kext has changed in Catalina, it no longer matches to EC. Here's a screenshot of the plists compared between Mojave (left) and Catalina (right).

The upshot of this has been that I don't need EC or USBX to get USB power. I've added a section for AppleBusPowerController to the top of my SSDT-UIAC:

 

DefinitionBlock ("", "SSDT", 2, "hack", "_UIAC", 0)
{
   Device(UIAC)
   {
       Name(_HID, "UIA00000")

       Name(RMCF, Package()
       {
           "AppleBusPowerController", Package()
           {
               "kUSBSleepPortCurrentLimit", 
               0x0834, 
               "kUSBSleepPowerSupply", 
               0x125C, 
               "kUSBWakePortCurrentLimit", 
               0x0834, 
               "kUSBWakePowerSupply", 
               0x125C   
           },

 

Works great, charges iPhone and iPad just fine and reports the extra current in system profiler. SSDT-EC and SSDT-USBX have been removed from my ACPI patches.

Hi MaLdOn,

How to add Ewerd's section for AppleBusPowerController in the SSDT you made for my Z390 Aorus Master? Or could you do for me, please.

Thanks in advance

Sorry for my bad english: I don't understand well. You means that your DSDT contains same patch for AppleBusPowerController, Right?
