附加信息:
(1)gscan2pdf
有xsane
同样的问题 - 找不到设备
(2)当我使用 xubuntu 12.04 扫描仪时
(3)如果我将笔记本电脑(与台式机一样是 Ubuntu 16.04)连接到笔记本电脑是 64 位,台式机是 32 位) 然后就可以在笔记本电脑上进行简单的扫描了。

请注意,如果我将扫描仪插入不同的 USB 插座(例如,总线 001 中的插座),lsusb
会在那里找到它,但简单扫描仍然不起作用。
附加信息:我可以将这台机器双启动到旧版 Fedora-3。扫描仪在那里工作。但是,scanimage -L
找不到它,lsusb
但sane-find-scanner
确实找到了。请参见 Fedora-3 启动时终端的以下输出。

是否可能导致libusb
FC3 能够运行扫描仪但 Ubuntu 16.04 无法使用libusb
?
正如我之前提到的,扫描仪在 12.04 上可以工作,但在升级到 14.04 后停止工作,现在升级到 16.04
有关 libusb 的其他信息:
32 位台式机(扫描仪不工作)和 64 位笔记本电脑(扫描仪工作)的终端输出相同,如下所示:
janos@acerlinux:~/Desktop$ dpkg -l libusb
dpkg-query: no packages found matching libusb
事实上,我刚刚检查过我的 64 位笔记本电脑没有 libsane-dev,并再次检查,如果连接到笔记本电脑,扫描仪就可以工作。
从以下评论中复制的附加信息:
/etc/sane.d/dll.conf
没问题,hp5590 没有被注释;然后我/etc/sane.d/hp5400.conf
通过添加正确的 usb 线进行了修改;扫描仪仍然无法工作,即使scanimage -L
检测到它,但报告为繁忙。请参见此处:

janos@AndrasXubuntu:~/Desktop$
还有一件有趣的事情,该/etc/sane.d/hp5400.conf
文件在 64 位笔记本电脑和 32 位 Fc3 台式机上是相同的,无需编辑添加 5590 usb 线,但自从 12.04 升级以来,两者都可以与扫描仪一起使用,除了 32 位 Ubuntu 台式机。
因此,我认为最大的问题是“为什么 32 位 16.04 Ubuntu 桌面报告设备繁忙?”
附加信息-修改了 libusb 的输出,这次带有星号:

附加信息:
根据我对 FC3 和 man sane-usb 的说明,必须安装 usbfs 才能使扫描仪工作。因此,在我的 FC3 中,我在 fstab 中有一行包含
none /proc/bus
。因此,我查看了 32 位 Ubuntu 和 64 位 Ubuntu 上安装的文件系统。参见以下比较:

答案1
我没有那个特定的扫描仪可供测试,但研究表明,特定型号需要使用sane-hp5590 后端由包提供libsane-dev与 sane 一起运行。安装该软件包应该可以解决您的问题并允许您正常配置 sane。
笔记:这我可以在这个后端找到的第一个文档表明它最初是为 64 位系统设计的,基于它所放置的文件 /usr/lib64/sane/
32 位版本有相同的文件,/usr/lib/i386-linux-gnu/sane/
因此看起来它受支持。但是我无法确认或否认这一点,因为我没有可用于测试的硬件。这可能很快就会成为一个没有实际意义的问题,因为 32 位支持即将消失,这一点已经变得非常明显。请参阅故事在这里和一个32 位处理器列表已经删除
有时扫描仪会得到默认未启用的合理后端的支持。启用它通常可以使事情正常进行。
检查以确保您的扫描仪受支持这里。在您的情况下,4500C 被列为完全支持,而 5500C 被列为未经测试。
/etc/sane.d/dll.conf
通过编辑并取消注释或添加该行来启用适当的后端hp5590
(如果有疑问,请检查其他 Linux 上上述文件中的工作配置以获取线索)完成编辑任务后,保存并关闭文件。
继续运行该命令sane-find-scanner
(如果这不起作用,则可能是权限问题,在这种情况下,您可能会得到不同的结果sudo sane-find-scanner
该命令的输出将如下所示:
# 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=0x01aa [EXAMPLE], product=0x0001 [EXAMPLE SCANNER]) at libusb:001:003
# 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.
现在将扫描仪添加到后端配置文件:
每个合理的后端都有自己的配置文件。
下一步我们需要 sane-find-scanner 的结果。你可以忽略以井号开头的所有内容,但重要的是这一行:
在 libusb:001:003 处找到 USB 扫描仪(供应商=0x01aa [示例],产品=0x0001 [示例扫描仪])
我们需要将这两个值添加到扫描仪的后端,在本例中为示例后端。为此,使用以下命令以 root 身份启动 gedit:
gksudo gedit /etc/sane.d/hp5590.conf
(通过检查来仔细检查conf文件的拼写是否符合你的情况ls /etc/sane.d
)
- 找到以下行:
usb
在其后我们需要添加一行,其中包含单词“usb”,后面跟着供应商编号和使用 scanimage -L 命令获得的产品编号。该行应类似于以下内容:
usb 0x01aa 0x0001
或者根据您的情况usb 03f0:1205
(根据您的lsusb
输出。)
编辑:如果其他方法都失败了,你可以尝试为您的版本推荐 32 位 libsane-dev 包。然而,这是否会成功可能取决于这个错误我建议您订阅它,以便开发人员可以最好地优先考虑他们的工作。

答案2
我在 Debian 上使用 HP 扫描仪 (HP DeskJet 1050A) 时也遇到了同样的问题。修复这个问题的方法是
sudo adduser <user> lp
sudo apt-get install libsane-hpaio
- 注销并重新登录(获取
lp
权限)
