使用 sane-find-scanner 检测到扫描仪，但未使用 scanimage -L 或 sudo scanimage -L

Question

我有一台富士通 ScanSnap S1300i。我从源代码编译了 SANE。当我运行时sane-find-scanner，给出以下输出：

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.

found USB scanner (vendor=0x04c5, product=0x128d) at libusb:002:004  
Your USB scanner was (probably) detected. It may or may not be supported by SANE.
Try scanimage -L and read the backend's
manpage.

Not checking for parallel port scanners.
Most Scanners connected to the parallel port or other proprietary ports can't be detected by this program.
You may want to run this program as root to find all devices. 
Once you found the scanner devices, be sure to adjust access permissions as necessary.

但是，当我运行scanimage -L或sudo scanimage -L给出以下输出时：

No scanners were identified. If you were expecting something different. 
Check that the scanner is plugged in, turned on and detected by the sane-find-scanner tool (if appropriate). 
Please read the documentation which came with this software (README, FAQ, manpages).

此外，我/etc/sane.d/fujitsu.conf为 ScanSnap S1300i添加了一个条目。

Answer 1

从我在官方理智页面上看到的，ScanSnap S1300 使用epjitsu，而不是fujitsu后端。您可以尝试将配置条目从fujitsu.conf到epjitsu.conf同一文件夹中的文件。

我不确定 S1300 和 S1300i 之间到底有什么区别，所以你可能需要*.nal从富士通 Windows 驱动程序中提取固件文件，就像在两者fujitsu.conf和epjitsu.conf文件的标题中所说的那样/etc/sane.d/，如果你还没有这样做的话.

更新 我只记得当我从源代码构建 sane 时，因为我需要新版本的扫描仪才能运行，我必须创建一个新的 udev 规则才能使扫描仪可用。

在 /etc/udev/rules.d 中创建一个名为 40-libsane.rules 的新文件，并将以下行添加到文件中：

ATTRS{idVendor}=="AAAA", ATTRS{idProduct}=="BBBB", ENV{libsane_matched}="yes"

将 AAAA 和 BBBB 替换为您扫描仪的 ID。您可以通过键入来查看它们lsusb（实际上，它与您所说的用于在 fujitsu.conf 中创建新条目的 ID 相同）。
