USB Port Monitor is a desktop software tool designed to capture, display, and analyze data traffic between USB devices and a computer. It operates by intercepting USB communication at the driver level, allowing users to observe requests, responses, and data packets exchanged during device operation. The software is used for debugging USB‑based applications, diagnosing hardware communication issues, and validating device behavior. It is intended for technical users who need detailed insight into USB data flows without modifying device firmware or applications.
