When a USB mouse is connected how does the system tell it's a mouse? Does it send some signal?
I need to implement (something like) a little mouse using an fpga board. I can output x and y coordinates from the board. How do I take the input x and y coordinates from the board and tell the system to control the mouse using them? I think I need to tell the system to treat the board as a mouse. How do I do that?
To be exact: it's a touch screen using proximity sensors.
Edit: The board is an "Altera Cyclone 4 DE2-115"
Edit2: We're using Verilog
