Hi,

how can I remove a kernel module from the blacklist in configuration.nix ?

I want to try if I can access to my samsung scanner by removing usblp from the blacklisted modules

NixOS/nixpkgs/blob/8b0bc7ce83bf2d39af03e1f2803eccfb04409e8d/nixos/modules/services/printing/cupsd.nix#L325


      
                if (action.id == "org.opensuse.cupspkhelper.mechanism.all-edit" &&
                    subject.isInGroup("wheel")){
                    return polkit.Result.YES;
                }
            });
          '';
          
          
# Cups uses libusb to talk to printers, and does not use the
          # linux kernel driver. If the driver is not in a black list, it
          # gets loaded, and then cups cannot access the printers.
          boot.blacklistedKernelModules = [ "usblp" ];
          
          
# Some programs like print-manager rely on this value to get
          # printer test pages.
          environment.sessionVariables.CUPS_DATADIR = "${bindir}/share/cups";
          
          
systemd.packages = [ cups.out ];
          
          
systemd.sockets.cups = mkIf cfg.startWhenNeeded {
            wantedBy = [ "sockets.target" ];
            listenStreams = [ "/run/cups/cups.sock" ]

Thx
