By the way, before use this new fix kext, the other BT4.0 device of mine, "MINIJAMBOX by Jawbone", which is a audio device on BT4.0, works perfactly fine. I suspect that for the situations I've encountered previously, the error only occurs when the pairing process is complex (such as when a pairing code needs to be entered, like a keyboard).
I added this kext after IntelBluetoothInjector and IntelBluetoothFirmware.
