我最近重新安装了操作系统，从 22.04 升级到 24.04。重新安装后simple-scan，我首选的扫描软件（通过 USB 直接连接的）无法再检测到我的 Fujitsu (Ricoh) fi-800r。simple-scan此配置在之前的 22.04 安装中运行正常。

笔记
  • 从 Ricoh 网站安装最新的驱动程序（pfufs/now 2.8.0 amd64 [installed,local]）
    • ls /usr/lib/sane/节目libsane-pfufs.so libsane-pfufs.so.1 libsane-pfufs.so.1.1.24
  • lsusb报告我的扫描仪Bus 009 Device 005: ID 04c5:15fc Fujitsu, Ltd
  • ls -l /dev/bus/usb/*/*报告足够的权限crw-rw-rw-+ 1 root root 189, 1028 Aug 28 09:40 /dev/bus/usb/009/005
  • SANE 记录了扫描仪的支持情况。

从apt list *sane*：

libsane-common/noble,noble,now 1.2.1-7build4 all [installed]
libsane-dev/noble,now 1.2.1-7build4 amd64 [installed]
libsane-dev/noble,now 1.2.1-7build4 i386 [installed]

xsane-common/noble,noble,now 0.999-12ubuntu4 all [installed,automatic]

从sane-find-scanner：


  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

  # Your USB scanner was (probably) detected. It may or may not be supported by

从scanimage -L：

device `pfufs:fi-800R:009:005' is a  fi-800R scanner
  • /etc/sane.d/dll.conf有fujitsu（未注释掉）
    • /etc/sane.d/fujitsu.conf有usb 0x04c5 0x15fc
  • xsane可以成功扫描图像。
  • 打开时simple-scan下拉菜单中没有列出我的扫描仪。
  • simple-scan pfufs:fi-800R:009:005尝试开始扫描时打开超时。
