Using AI to reverse engineer hardware drivers for a film scanner and laptop camera

ErenayDev describes using Claude to build Linux drivers for a Plustek OpticFilm 8200i negative scanner and a MIPI camera on a ThinkPad X1 Carbon Gen 14.

The method records a reference session of the Windows driver in a KVM virtual machine, captures USB traffic on the Linux host with usbmon, and diffs the two traces.

The author reports a working SANE backend, a GNOME negative-scanning app called Negative Vibes, and kernel and libcamera patches for the camera, and publishes the generic hw-harness tool.
