Developer seeks help reverse-engineering Barrot Bluetooth in macOS Ventura VM
A developer is investigating why a Barrot Bluetooth adapter (0x08E7) fails to become the active controller in macOS Ventura running on VMware Workstation, despite successful USB passthrough and raw HCI communication. The adapter mimics CSR hardware but requires a special initialization sequence, and existing tools like BlueToolFixup don't help. The developer is seeking collaborators familiar with Apple's Bluetooth stack, IOKit, or DriverKit to diagnose the issue.
