Legacy Peripheral Integration in Modern Operating Systems: A Case Study of the HP ScanJet 2400 Driver on Windows 10 Author [Generated for academic simulation] Abstract The HP ScanJet 2400, a USB flatbed scanner released in 2004, lacks official driver support for Windows 10. Despite this, thousands of users continue attempting to operate the device on contemporary systems. This paper investigates the technical, historical, and socio-technical reasons behind this persistence. We analyze driver compatibility layers, community-sourced solutions (e.g., VueScan, Windows Image Acquisition (WIA) fallbacks, and modified .inf files), and the underlying USB protocol mismatches. Our findings suggest that the absence of native drivers is not solely a technical obsolescence but a strategic product lifecycle decision. We propose a generalized framework for diagnosing legacy peripheral support in Windows 10. 1. Introduction The HP ScanJet 2400 was released during the transition from parallel to USB 2.0 interfaces. Its driver architecture was built for Windows XP (x86), with later Vista and Windows 7 support provided via compatibility shims. With Windows 10’s driver signature enforcement (DSE) and removal of legacy kernel-mode drivers, the original HP driver fails to install or crashes the WIA service.
