It’s possible it’s just a normal usb device, some touchpads are. Your best bet to find out, is to identify that driver chip.
It says this on the chip but I can't find any info about it
It’s a Synaptics S9561 (S8561?), I don’t see a datasheet though. You might need to just reverse engineer it and see what on the laptop side it connects to and see if that chip can be identified.
The company name is Synaptics. A search for Synaptics S9561 finds a hit on Synaptics Touch Controllers but I couldn't find any datasheet for the chip.
This might give you some hints:
thanks for the help ill try and get it working with the info i have now
Perhaps the statement on the Synaptics website stating they do CUSTOM designs for their customers answers the question.
