You can find a working experiment USB4 devices with SSDT only TBT bus here from @dehjomz Detected as Thunderbolt 4 downstream … plus USB4 mode enabled on System information :)

I think that IOThunderboltSwitchUSB4, IOThunderboltSwitchType6 & IOThunderboltSwitchOS don't use Link Controller, only on IOThunderboltSwitchType 1,2 & 3 (Thunderbolt 1,2 & 3)

This could be a partial response. As you have an USB4 device that use PCIe downstream, You can try flashing with a modified firmware that include port@C & port@D enabled... this also may not work.

@joevt from Thunderbolt DEBUG Log of CaseySJ's ASUS ProArt Z690, I have found this : (AppleThunderboltDPOutAdapter) 1427806us AppleThunderboltDPOutAdapter<<private>>::start - fDPMaxHBRBandwidth = 80 and found this from DisplayPort Wiki : This may help for HBR3 compatibility :) ?

Thanks ! If you have some time, can you attach thunderbolt debug log for Big Sur ?

Hi @CaseySJ We can compare Thunderbolt Debug Logs on this two Systems ... Sometimes AppleVTD (Virtual memory protection) is enabled on NHI device, sometimes not ! This could be a research track

Message for all experimenters, is someone could post his Thunderbolt DEBUG Logs explain here with his ASUS Z690/Z790 without any Firmware patches ? I want to understand why macOS Thunderbolt drivers can deal with a disabled Thunderbolt Host Interface on port@7 :) If you can also make 2...

Hi @Inmike09 don't be so modest, you have discovered full Thunderbolt bus enabled without any firmware patches on modern macOS version for Asus Z790 mobo (then working on Z690) :thumbup:

Hi @KungfuMarek You can find all explain informations on this Post for Thunderbolt Bus ID customization.

Disassembled code doesn't lie :) .. As said, minimum value of 0x8 in 2021, with Titan ridge, we had 0x3 if I remember.

Hi @CaseySJ ... What can I say ?! Wow.. this is not a fake news ! Have your tried with GC-MapleRidge ?

Hi @taylorsyn Could you share an IOReg screenshot of DSB1 or DSB3 (which one is connected) & XHC3 (SSP1 or SSP2) when your LG monitor loose USB after the hotplug (no webcam and sound) ?

Hi @sihl32a from Switzerland, neighbour country :) We still have same error 0xe0002d6 like saw on @Inmike09 results. On disassembled code, redundant logs with this error code are related to "command time-out", I can't say more. Experimentation with unflashed firmware is new for Thunderbolt part...

As AppleThunderboltNHI driver is not loaded, you have something wrong with your SSDT (device-id and/or class-code spoofing).

Hi @beelzebozo if you are able to flash your GC-MapleRidge with CH341A programmer, you are welcome to test it and see if you have sleep issue on this mobo. All files (firmware & SSDT) are available on this thread. Thanks for testing !
