Hi team!
 
	I have almost dream machine. 
 
	I just can't win with Thunderbolt3 
 
	 
 
	Setup: 7480 i7 7th gen
 
	touchscreen
 
	3xUSB + 1x TB3
 
	macos 12.4
 
	TB3 device I try to use: Blackmagic ultrastudio 
 
	 
 
	I think my ports configuration is messed - but I tried to remap usbmap and this doesn't help.
 
	 
 
	If I connect USB 3.2 Stick to Thunderbolt port - this is detected correctly
 
	If I connect Thunderbolt 3 device - this is not detected at all.
 
	If I connect USB 3.2 usb stick to top left usb port - this is not detected - but usb 2.0 device is detected correctly. I can live with it though 
 
	I attached both IOREG files with connected usb stick and connected thunderbolt device. 
 
	I exluded cable problem as I have a dualboot and same setup works perfectly fine with Win10 boot.
 
	 
 
	I don't need hotplug - as long I have working TB3 I will be more than happy. Please see my  configs. 
 
	 
 
	Any help will be appreciated.
