This paper explores the software architecture required to facilitate communication between a host system and a Universal Serial Bus (USB) gamepad. While modern operating systems utilize generic Human Interface Device (HID) drivers, understanding the underlying USB protocol, descriptor parsing, and data packet interpretation remains critical for hardware designers, driver developers, and those creating low-latency input pipelines. This document details the flow of data from the USB electrical layer to the application-level API, focusing on the standard HID class driver model.
