I'm essentially creating a new way to control the cursor on the screen. Right now I have an Altera Stratix iv FPGA, and I'd like it to send information via USB to the computer and control the cursor.

Is this doable, and does anyone know of something similar? What will this end up looking like? I realize that I may have to write some code on the machine that listens over the port and moves the mouse, I'm fine with that, but is it possible to move the mouse with code that sits on the FPGA?

Thanks!

You're probably going to want to implement a USB HID class device. The HID class is one of the simplest kinds of USB classes, and most USB kits come with an example HID device. The benefit is that your OS will already know how to talk to a HID device, so you won't need to write any OS drivers.
