Jumpers are right. "Thunderbolt/USB4" field in the System report makes no sense. You should test it with a Thunderbolt device.

I tested Thunderbolt ports with a Thunderbolt device (portable hard disk). Hot plug worked and the link speed was great. The only problem is that the Thunderbolt device can not be recognized with cold-boot. I have to re-plug the cable to get it to work. How to get the device recognized when...

By the way, I also tried to hot plug my Android phone, and data in the phone could be recognized by Android File Transfer. It also appeared as a USB 2.0 device in the system information. But another Android phone did work that way. Interesting!

It does not work, even unbootable. Maybe I should try Gigabyte GC-Alpine Ridge add-in-card. Does that card work well with USB 3.1 hotplug?

I will try it. Does NVM 33 for Designare Z390 support JHL7540 too?

A breakthrough has been made! In System Information --> PCI, intel JHL7540 Titan Ridge Thunderbolt 3 NHI and intel JHL7540 Titan Ridge USB 3.1 appeared. USB 3.1 device does not work. I do not have a Thunderbolt device now. I will buy one and test it tomorrow.

Thanks for your patch. I tried and there was my system information about this card. No thunderbolt device plugged. Is the card working well?

Thanks a lot. I will try it later and post my result.

Here is my IORegistryExplorer content. No Thunderbolt SSDT applied.

File attached. Thanks for your help!

Thank you for your answer！ Another question is how to adapt the SSDT for the actual PCIe path for my system? For example, see the screenshot below. There is nothing similar with PCI0.RP05(I found BR1A under PCI0). In this case, what PCIe path should be correct? Thanks again.

First of all, thanks for the great work you have done here. Below is my question. After flashing DROM and plugging the Thunderbolt card in my system, there is no Thunderbolt root port found.(Thunderbolt card connects to the CPU directly.) I can not customize PCI and RP in this DSDT and...
