[Query Fix] Port Discovery and uia_exclude boot flag

[Montelli]

Hello,
as the title I need help for port discovery in High Sierra and for exclude useless usb on my pc desktop, I tried the following boot flag but I did not understand if it worked:
uia_exclude = HS01; HS02; HS11; HS12; USR1; PRT1, PRT2, PRT3
I attach the ioregistryreport screens, maybe you can help me because I do not understand if there are any other USB ports to be excluded or if the ports inserted in the FLAG have been excluded
I await a cordial reply,
Best regards

The uia_exclude flag affects only the devices for which USBInjectAll.kext is injecting ports.

I use the kext USBinjectall, but then which ports injected USBInjectAll.kext?
Can you tell me? Because from the screens I can not understand

@Montelli, please update your profile (personal details) with your Motherboard, CPU and Graphics Card.
If you have a prebuilt computer enter make and model instead of motherboard (Mobo).

Profiles need to contain at least your primary system to assist others with helping you.

Sorry...Now I've updated the signature, I await your help
Thanks

See guide:

But instead of creating ssdt, can I just use the uia_exclude boot flag?
(From the screens what ports injected the USBInjectAll.kext? first I was asking you how to use it, as you see by the screens I discovered the ports that work but I did not understand which I should to disable because there are several strings)

The USBInjectAll.kext covers all the injections that USBInjectAll does (EH01/HUB1/EH02/HUB2/XHC).
Excluding ports is only part of proper USB configuration. You must also set the UsbConnector (and portType for hub ports) values to match the port usage.
