On my own system (this is a full Guix System, not Guix on a foreign distro)= I modified the configuration.scm: ```scheme (use-package-modules #;... scanner) (operating-system #;... (services (append #;... (modify-services %desktop-services (sane-service-type _ =3D> sane-backends)))) #;...) ``` After `sudo guix system reconfigure configuration.scm`, `simple-scan` still= could not find it. However, on reboot, it was able to find my already-con= nected USB printer/scanner without any issues. Perhaps only some kind of force-trigger of `udev` would be needed after the= above setup, but `udev` is pretty early in the Shepherd tree. On the other hand the `sane-service-type` documentation in `info guix` is *= **severely*** lacking, and the documentation is somehow lost in the middle = of documentation about geolocation services, so it should probably be fixed= .
