Hi Juhne, thanks for you reply, really appreciated.
No, with
@RehabMan SSDT you don't change anything.
The SSDT refers to a specific controller, in this case XHC SSDT-UIAC-USB-8086_a2af
Usually if you switch from one SMBIOS to the next you have to change nothing with this method given that you pick the right controller type at the very beginning.
Even though I applied the 10.14.5 USB patches and the controller is the a2af port HS13 and HS14 are gone as well as the USR1 and USR2.
Bluetooth happens to be in the HS13 so with SMBIOS 19,2 that is gone.
Strange.
