DW1560 bluetooth on Catalina 10.15.1

If you see "Firmware = v14 c4096" in About this Mac, you're firmware didn't update the BT card. DW1560 downloads firmware upon every boot. Rehabman and AcidAnthera explain this on their GitHub readme in the beginning (RAMUSB). In short:

BrcmFirmwareData: loads upon boot
BrcmPatchRam3: uploads firmware
BluetoothInjector: injects info to macos

You need these 3 to properly load BT and upgrade firmware. This is why when you login to Windows or Linux, then restart onto MacOS, you get Bluetooth working properly. It's the RAMUSB firmware that got updated in Windows or Linux. Turn off your computer, login to MacOS, you're connectivity issue will be back.

the "repo" kext does not belong in there

also you have both USBInjectAll.kext and usbports.kext

if you have setup your ports correctly, then USBInjectAll.kext should be deleted
