| Step | Status | |------|--------| | Verified Rockey4 VID/PID in Device Manager | ☐ | | Downloaded Rockey4 driver v4.15 (not generic) | ☐ | | Disabled driver signature enforcement (temporary or via bcdedit) | ☐ | | Manually installed driver via “Have Disk” | ☐ | | Rebooted and checked Device Manager for “Rockey4 USB” without warning | ☐ | | Tested actual software (not just driver installation) | ☐ | | Considered VM fallback if driver fails after next Windows update | ☐ | The Feitian Rockey4 is a relic of an era when dongles ruled software protection. Windows 11, with its hardened security model, treats these old drivers like intruders. While there is no “official” Rockey4 USB driver for Windows 11, the methods above provide a functional—if imperfect—bridge between legacy licensing and modern operating systems.
