USB 3 Not Working on Skylake Desktop

[ethanguy1000 0]

Hello, I just installed Hackintosh shop Big Sur a few days ago. Sound, internet, and iMessage all work, but I cannot get the USB 3.1 ports working. USB 2.0 devices work fine in those ports, but USB 3.1 devices will not show up when inserted. This was not an issue when using Niresh Catalina without any tweaks.

I used the EFI boot loader for Skylake Desktop that was already on the bootloader when I imaged my installation drive. My specs are as follows:

Asus z170-p motherboard, i5 6600k, 8x2gb DDR4-2400, RX 480

Any help would be appreciated. Thanks.

USBInjectAll.kext is one of the solution.

You might want to create SSDT for your USB/Motherboard

UPDATE: Fixed by switching to OpenCore. Running Big Sur from a USB Drive is not 100% stable (I needed to use a SATA drive to install and update, then transfer using a disk cloning software), but it works and I'm happy with it.
