i am using this product Smart Cat PRO MOUSE(GP415U-5321), i am attached to my STM32 evaluation board. Normal operation are working like Right,Left and center click but the external feature are not working(A,B,C,D,ZOOM,SCROLL,BACK and FWD). How the protocol format are working in touch-pad. The data length is 13 Bytes but only receive 4 bytes, not the full 13. How can the remaining Bytes be received? just give me some suggestion.
Thought about contacting the manufacturer of the touch pad and getting documentation and support from them?
Perhaps there are commercial USB stack vendors who provide integration support as part of the deliverables?
