NEW PARTIAL SUCCESS!
Everything except thunderbolt.
I have kind of cobbled a build together.
Boot works amazing. Everything seems to be ok. There was a random freeze that was occurring but I think that may have been fixed by disabling the vt-d.
-asus z390-a prime mobo
-intel i7 9700k
-ASUS ROG Strix Radeon RX570
-2x 16gb corsair rgb
-Samsung 870 evo
-fenvi t919 (wireless/bt) *wifi works/bt doesnt
-Titan Ridge 2.0
EDIT: BIG SUR INSTALL BTW
TO THE HEART OF THE ISSUE:
I am using a Focusrite Clarett 8pre
I have been able to get it to connect via windows.
It has connected like 4 times in the osx environment only to disconnect and not come back after altering for hotplug.
I have added the post install ssdt's
I modified the TB3 ssdt to coincide with the IOreg readings i am getting (RP17)
still nothing.
NO HOT PLUG, NO TB3 EVEN WITH IT PLUGGED IN ON BOOT
HEEEELPPP were coming on a week of me doing nothing but trying to get this thunderbolt to work
lemme know if i need to up any files plz and thank you!
