I need to use 5 external Bluetooth USB controllers. The system was developed on a Raspberry Pi 4 but that lack power for doing the graphics needed. I could disable the on-board BT easily, but I can't figure out how to disable the Z83-4U Bluetooth. I've tried rfkill to soft block the internal but bluetoothctl can still see it and can make connections. Can I blacklist the driver? If so, what is the driver name bearing in mind I still need WiFi?
