My root problem is bluetooth stopped working on upgrading to Catalina.
I have applied the latest USB 3.0 Inject kext to patch as referred to in

My Wi-Fi takes about 3+ minutes to initialize once the OS is booted. I suspect that also indicates a problem?
Here is the WiFi card:

Here is the BCM20702A0 (Bluetooth?) card seen on USB.

I don't see a place on github to download the release (or debug) versions of the .kexts call out by headkaze. There are 3 kexts expected for the fix: BrcmFirmwareData.kext, BrcmPatchRAM2.kext and BrcmBluetoothInjector.kext.
Is one expected to compile these from the github project? Has anyone got all three available?
The link by the way doesn't work.
