Some AMD laptop owners had to resort to using GenericUSBXHCI.kext to fix not being able to use their USB ports. This is an old USB kext, which was dropped from use on Intel systems some years ago. So not sure it will work, but may be worth a try to see if one or more USB ports are enabled so you can complete the macOS installation.

Download:

I can't recall if you have created a UTBMap.kext in Windows, using the USBToolBox python script. If not you may want to see if doing so helps. This is an alternative and better option than using the GenericUSBXHCI.kext.

Hi, I have some recent updates.
With the help of https://github.com/hbyonly1/XHCILagFix , the usb issue is resolved.
I can boot into the installation and recovery dmg right now.
But still having amd gpu driver issue during installation.

And I have also checked my gpu device properties on recovery mode and got this.

Here is my current EFI file. Still have no idea which part is not working. Any help on the direction of resolving this issue is appreciated. Thanks

I just fixed all the problems. Replacing the nootedred.kext with the latest version in my previous EFI would work. However the onboard speaker is still not working. Need to debug with CirrusAudioFixup.kext to fix
 
你nvidia gpu怎么驱动的啊?想问下你的内置摄像头能工作吗?
使用1401项目打的rtx3060驱动:https://github.com/nullmoth/1401 目前基本可用,还没测帧率,但是办公没问题。摄像头现在不可用,我还没尝试修复它。我修复了触控板,另外我用你的办法修复了我的电脑的USB。我现在正在想办法修摄像头和声卡

声卡修复要等这个
 
声卡修复要等这个
我的笔记本不一样,是暗影骑士龙2022,扬声器由 ALC287 驱动,板载声卡当前成功修复。rtx3060跑满1k165hz毫无压力。目前仅剩原生WiFi和蓝牙是一条死路,我打算买一个新的无线网卡,应该就完美了
