Posted by: [Your Name] Platform: Windows 11 Pro (Build 22621) Device: Generic USB 2.0 Multi-Card Reader (SD/MMC/MS/xD) 1. Background I’m working with a USB 2.0-based Card Reader Writer (CRW) device. Under Windows 10, the inbox driver ( USBSTOR.SYS + WUDFRd.sys ) works fine. However, Windows 11 has introduced stricter driver signing, power management changes, and removal of legacy bus drivers.
