macOS Catalina 10.15.0 - USB Port-Limit Removal Patch

Worked for my Gigabyte Z390M Gaming motherboard, thanks a lot!
 
With the release of macOS Catalina 10.15.0 you'll probably need a port-limit removal patch to begin your USB configuration on a new build.

Here it is:

View attachment 430312

As you can see we only need two patches for Catalina as opposed to four, for Mojave.

Line 1 -

Name*: com.apple.iokit.IOUSBHostFamily
Find*: 83FB0F0F
Replace*: 83FB3F0F

Line 2 -

Name* com.apple.driver.usb.AppleUSBXHCI
Find*: 83F90F0F
Replace*: 83F93F0F

Remember you will need USBInjectAll.kext installed to enable this to work.

Hi both.

I have checked for you today and - from this end - the original port-limit removal patch still works.

At this point I can only ask you double-check everything you can. If I learn more, then obviously I'll let you know :thumbup:
