Big Sur 11.3.1 update breaks USB 3.0

Hi all,


I have an issue with two different motherboards, one Asus Z370 and one Gigabyte Z390, and USB once I moved to Big Sur 11.3.1 from Mojave.
Both motherboard have USB definition AND with BOTH motherboard after update to 11.3.1 USB 2/3 doesn't work anymore.

I tested both motherboard with the .aml USB definition and with the hackintool kext.
I've also done in both cases a fresh new .aml and .kext using hackintool with the latest USBInjectAll but the problem persists.
I have reset NVRam but nothing changes.

What happens is there's port definition, the devices connected somehow show up in IOReg BUT they are not mounted, so they're unusable.
Though I can see the internal USB Bluetooth connection and bluetooth works. So might it have to do with the type of port?

Does anyone have an idea how to unlock USB again?

Thanks a lot for your help!

Hi there.

If you have a ready-made USPorts.kext then that should work with BS 11.3 and 11 3.1.

What is not working currently is the XhciPortLimit quirk, alongside USBInjectAll.kext. The OC devs know about this and are working on it.

If you have tested USBPorts.kext in your EFI folder and it still is not working then try re-creating it. Some builders prefer to use USBMap instead, but there's no real reason why it should be any better than USBPorts.

That's the issue.

XhciPortLimit quirk is switched off.
USBInkectAll.kext is the latest.
Then I have redone the mapping BUT with either of the two solutions, .aml or .kext, USB 3 doesn't work.
Devices don't connect.
If you llok at the attachment you see that the port are mapped, that somehow the USB device is seen BUt it's in red and not mounted.

I don't know if it's related but with OC 0.6.9 and BS 11.3.1, whenever I wake from a deep sleep, the USB fails to respond. It usually take 2 clicks from my USB BT mouse or keyboard to wake. The rig responds to the first click but fails to respond to any USB input on the second click (meaning the BT keyboard or mouse or a directly connected USB keyboard or mouse). Restarting and checking the logs, it looks like the drivers for the USB devices fail to load upon wake.

Rolling back to OC 0.6.8 has no problems at all. I don't really have time to dig into it, but I'm hoping with OC 0.7.0 it will be fixed.
