Hi all, I have XPS 9570 with i7-8750, 32GB RAM, 2TB NVME SSD and 4k laptop. I installed Catalina 10.15.3 using bavariancake EFI. All hardware is working perfect, except touchscreen and TB3. Thunderbolt is working but hotplug isnt and when i opened system report, i couldnt see any thunderbolt device (hotplug or not). I attached my debug file. Thank you all for efforts. debug_1488.zip

Few days ago, I clean install the 10.13.1 on my 5480, and the usb3.1 type-c hot plug works fine. yesterday I got the Dell TB15 (TB3 dock), then TB3 is no hot plug, I have to plug in before boot, and the type-c on the TB15 is no hot plug, either. any idea? Thanks
