I use a fenvi t919 and macOS Big Sur. Computer specs below and to the left. The bluetooth chipset is still supported. I have noticed many users posting about losing Bluetooth when going from 11.6.5 to 11.6.6.

Initially, an nvram reset fixes the problem and bluetooth is restored. Then, the next cold boot after that Bluetooth is gone again. Attached is the EFI I'm using if anyone has any ideas. I've tried re-mapping the USB ports and also swapped out USBports kext with the old USBinjectall to see if it made a difference--no luck fixing the bluetooth yet. The problem persists through 11.6.7 as well.

Any ideas or solutions much appreciated.
