Any luck? I want to do the same thing.
I can think of two issues with this.
1)The stock controllers have Bluetooth in them. How do we know the controller signal is sent through the USB port and not Bluetooth, when the USB is plugged in. Obviously it would make sense that it would go through USB for speed reasons, but maybe the USB is only used for charging so there is no issue of dropped packets when switching from wired to wireless communication.
- I believe the PS3 communication is encrypted. I am also aware that the signals can be (and have been) de-encrypted. However, once we mess around with the signals using the arduino, does the signal have to be re-encrypted to be sent? Has this been done before?
I hope someone can help us out with this.
