Hello, I've had success in probing the device with the aforementioned tool (https://github.com/bentiss/SimplePeripheralBusProbe). Sadly I'm not sure how to analyze the data. Hopefully someone else is able to make something out of it. I recorded the command which enables the numpad and the command to disable it. However, there are some more interactions which seem to happen regularly. If anything else is needed I will be happy to try to provide the data.
