What they did
The poster, u/Wizzard_2025 on r/ClaudeAI, owns a Canon CanoScan LiDE 30 flatbed whose last official driver was for Windows XP. For years they kept an XP virtual machine in VirtualBox just to scan. They asked Claude to make the scanner work on Windows 11 64-bit. Claude produced a WIA driver package built partly on code from a GPL Linux scanner driver, plus an install script that opens a PowerShell window and explains each step as it goes.
How it went
The scanner worked on Windows 11 after roughly an hour of work. It shows up in Windows Fax and Scan and can be used from MS Paint, but the newer Windows Scan app does not see it. The poster shared the package (version 0.2.5) as a zip so other owners of the same model could try it. They give no other numbers.
Worth knowing
Because it reuses GPL Linux driver code, the poster has to ship the source along with it. Windows requires signed drivers, so the installer signs it during setup and then deletes the private key so the certificate cannot be reused. The post does not say which Claude app or harness was used. Installing a driver from a shared zip means trusting code you did not review.
