Thank you very much. It worked. But some ports are missing. Have you got all ports worked? My internal ports are still not working

[zhang-wenchao]

macos 15 port limit，you try USB Port Limit Patches

i used 15 port limit patch. but some ports didnt recognized automatically. i mean internal usb ports and front usb3.0 ports didnt get recognized. but i created ssdt for usb. it is perfect now.
advice: dont use 15 port limit patch as a permanent solution. use it for just mapping your ports. then make your own ssdt for usb. then disable 15 port limit patch.

here is my ssdt.
