I can't get my USB bluetooth [0a5c:21e8] to work.

It shows up in USB devices under system information but it does not function (LED is on). It is also my active bluetooth device as shown in the bluetooth section under system information.

I tried installing BrcmPatchRAM2.kext and BrcmFirmwareRepo.kext after that. Now it is not my active bluetooth device (does not show up under the bluetooth section).

I tried Bluetooth Explorer (Additional Developer Tools for xcode 8.2) to set the BCM20702 as active but that does not work, my internal bluetooth stays active. Then I tried this in terminal and a reboot:
sudo nvram bluetoothHostControllerSwitchBehavior=always
Still not active.

Is there anything I can do to fix this?

Your ioreg shows two bluetooth controllers.
Not a good idea.
Broadcom at HS04 and another (Intel) at HS07.
Disable the Intel device via BIOS or with USBInjectAll.kext (custom SSDT).

It worked by disabling HS07 with the custom SSDT, thank you!
Now if I want to complete the custom SSDT, are USB type c devices also defined here? I don't have any usb type c devices to connect currently so I cannot check.

Get a USBC->USB3/A adapter so you can test the USB-C port(s). Make sure you test in both orientations. Further clues in the ACPI spec (for UsbConnector value, etc).
