Provided are an apparatus and method for diagnosing operating system resources supporting universal serial bus (USB) device driver development for a Linux system. The apparatus and method device enable driver developers to simply perform, without professional knowledge of hardware and operating systems, operating system resource diagnosis such as detection and extraction of hardware information required for device driver development, search and change of various descriptor configurations, and process of data input/output through an endpoint. Thus, effort and cost required for a device driver development process are reduced, and it is possible to improve the efficiency of Linux USB device driver development work.
