问题描述
我正在尝试使用具有扫描仪的打印机三星scx-4200进行扫描。当我连接具有相同版本ubuntu(14.04)的兄弟的笔记本电脑时,它可以工作。我不知道如何以及为什么。他没有安装任何扫描软件。我还尝试了另一台使用基本操作系统的计算机,它也可以工作。现在是时候变得很奇怪了!我试图在我的和兄弟的笔记本电脑上运行许多通过实时USB发行的发行版。扫描仪始终可与Brother一起使用,而不能与我的笔记本电脑一起使用。我非常需要扫描仪,因此可能会切换到Windows,这是我不喜欢的,因为它不是开源的,所以请帮忙!这是我遇到的错误以及简单扫描设置的屏幕截图。
编辑1:USB可以与任何其他设备正常工作。到目前为止,我已经连接了鼠标,USB闪存,相机,并且它们都可以正常工作。我试图将扫描仪连接到所有3个USB端口(2 3.0和1 2.0),并且发生相同的事情。
Edit2:扫描与程序vuescan一起使用,但是需要购买它才能删除它创建的水印,并且该水印是封闭源。
Edit3:在所有经过测试的笔记本电脑中,只有我的笔记本电脑具有USB 3.0(x2)。但是,扫描也不适用于USB 2.0(在我的笔记本电脑上)。
Edit4:这是sudo sane-find-scanner
的输出:
# 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.
# No USB scanners found. If you expected something different, make sure that # you have loaded a kernel driver for your USB host controller and have setup # the USB system correctly. See man sane-usb for details.
# Not checking for parallel port scanners.
# Most Scanners connected to the parallel port or other proprietary ports # can’t be detected by this program.
Edit5:我尝试了BIOS中与USB配置相关的所有设置组合,但没有结果。我恢复了原始设置。
Edit6:我尝试了scanlite,这是它给我的错误:
Edit7:第二次运行Scanlite时,它说它没有检测到计算机上的扫描仪。我有时会在简单扫描中得到类似的消息。
Edit8:执行以下操作后,扫描仪即可进行简单扫描:
-
打开系统设置
-
点击打印机
-
右键点击我的打印机(scx-4200)->物产
-
墨水/墨粉量
-
单击刷新
-
打开简单扫描
-
点击扫描
-
等待大约10到20秒,直到出现错误消息(如提供的屏幕截图所示)
-
再次点击扫描
那仅用于1次扫描。
Edit9:我和我的兄弟都有64位。我兄弟的笔记本电脑是hp,而我的笔记本是华硕。我的BIOS有更多选择。我有2个USB 3.0和一个2.0,而我的兄弟有3 x 2.0。这是一些区别…这是我的笔记本电脑的uname -a输出:
Linux dusan-K55A 3.13.0-24-generic #46-Ubuntu SMP Thu Apr 10 19:11:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
这是我兄弟的:
Linux milki-HP-2000-Notebook-PC 3.13.0-24-generic #46-Ubuntu SMP Thu Apr 10 19:11:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
Edit10:我的笔记本电脑是全新安装的,兄弟的笔记本电脑已升级。当两台笔记本电脑都运行全新安装13.10时,发生了相同的事情
Edit11:这是我的lsmod
的输出:

它找到打印机(scx4200),所以我猜它也是扫描仪,因为它是打印机和扫描仪(多功能打印机)。

Edit13:通过分析/var/log/kern.log中的错误,我发现当我发现没有扫描仪的错误时,此错误行将输出到kern.log中:
May 6 20:45:34 dusan-K55A kernel: [ 500.209280] usb 3-3: usbfs: interface 1 claimed by usblp while 'scan-thread' sets config #1
当出现“无法扫描”错误提示时(如屏幕截图所示),我得到此错误:
May 6 20:52:03 dusan-K55A kernel: [ 889.843120] usb 3-3: usbfs: interface 1 claimed by usblp while 'scan-thread' sets config #1
Edit14:我意识到使用我通过this link安装的Samsung Universal linux驱动程序,无法进行打印。我通过在系统设置中添加打印机功能卸载了它并安装了驱动程序->打印机。但是,即使使用edit8中的步骤,现在扫描也不起作用,该步骤以前可以工作,但现在可以打印。 A但是,使用vuescan扫描仍然有效。
Edit15:这是grep 341b /etc/sane.d/xerox_mfp.conf的输出:
usb 0x04e8 0x341b
并输出modprobe -r usblp; 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

您的USB 2.0设备(在本例中为扫描仪)与USB 3.0系统(USB3端口或USB3集线器的USB2端口)进行交互时存在一些兼容性问题。该问题可能是由扫描仪硬件/固件,PC EFI /BIOS固件,PC USB芯片组或Linux内核xhci_hcd驱动程序引起的。
可能的解决方案:
-
使用短的USB 2延长电缆(或仅使用USB2电缆)连接设备。这将强制USB 3端口使用USB 2信令。 USB 3设备或电缆具有9针,而USB 2设备或电缆仅具有4针。仅连接4个引脚时,USB 3端口将默认为USB 2信号通信。一根USB 2延长线仅会缠绕4根线,这些线连接了仅USB 2通讯的4个引脚。
-
使用便宜的USB 1.1(或2.0)集线器并将其连接到USB3端口。将设备连接到USB 1.1 /2.0集线器。这将强制连接为USB1.1 /2.0。由于集线器具有不同的USB控制器,因此可以解决一些协议错误。 USB 1.1集线器是”low speed”设备(如鼠标,键盘等)的不错选择。USB2.0集线器对于”full speed”设备(如不会降级到USB 1.1的扫描仪)非常必要。
-
升级您的PC /笔记本电脑BIOS。制造商可以解决BIOS /EFI中的许多USB问题。
-
如果笔记本电脑有USB 2.0设备(扫描仪),请通过USB 2.0端口连接。如果您的USB2端口也由xhci_hcd驱动程序控制(即,您在dmesg中仍然看到
new high-speed USB device number x using xhci_hcd
),则这可能没有什么不同,在这种情况下,请尝试使用外部USB2集线器。 -
如果这是台式机或服务器,而不是笔记本电脑,请尝试使用其他PCI USB控制器卡。不同的USB3卡具有不同的XHCI主机控制器芯片,因此与不同的USB集线器/设备的兼容性也有所不同。
-
升级USB 2.0设备的固件。对于consumer-level扫描仪,这可能是不可能的,但是对于某些USB 2.0设备(例如,专业相机),这是可能的。
-
将USB 2.0设备(扫描仪)替换为USB 3.0兼容设备
-
在USB配置下的UEFI /BIOS change the setting中,“ XHCI预引导模式”从启用更改为禁用。在某些BIOS配置中,此设置称为”XHCI Mode”。 USB 3.0端口由Linux中的xhci_hcd驱动程序控制。启用“ XHCI预引导模式”后,BIOS会将USB 3.0端口路由到USB3 xHCI controller。禁用后,USB 3.0端口将路由到EHCI(USB 2.0)端口。措词“预引导模式”表示此选项仅在引导完整的操作系统之前影响环境(相关的BIOS帮助文本明确提到此选项用于MSDOS中的USB3支持);但是,这似乎也可能会影响post-boot环境,即使加载了Linux,也可能具有将USB 3.0端口连接到USB 2.0控制器的效果。这样做的缺点是所有USB 3端口现在都将以USB 2速度运行。

对于具有autosuspend内核模块选项:
modprobe usbcore autosuspend=-1
的所有设备,为Disable USB powersaving或如果usbcore不是具有以下内核引导参数:usbcore.autosuspend=-1
的模块(在Ubuntu中是内置的,则使用内核引导参数) -
禁用扫描仪的节电功能(USB自动挂起)(来自Documentation/usb/power-management.txt)。将扫描仪插入支票
dmesg|tail
时,您会看到类似usb 3-3: Product: SCX-4200 Series
的数字3-3
表示设备的USB路径,格式为bus-port.port.port。相应的sysfs目录位于/sys /bus /usb /devices /3-3。在此处写入电源/控制以禁用自动挂起:echo on > /sys/bus/usb/devices/3-3/power/control

在32位Ubuntu 14.04上,我的扫描仪(全部位于一个Brother MFC-j410中)遇到类似的问题。扫描仪仅在第二次启动XSANE之后才能工作,然后只能进行一次操作预览或扫描。我尝试将USB端口更改为USB 2.0,但无济于事。我的主板是带有Intel i3 LGA1150芯片的Asus B85M-k。
我在早期版本的Ubuntu中尝试了virtualbox,其中扫描仪始终可以在另一台PC上运行。尽管如此,还是没有运气,这使我对USB 3功能非常怀疑。打印机也给了我一些警告,但确实打印了。

USB 3.0端口由Linux中的xhci_hcd驱动程序控制。启用“ XHCI预引导模式”后,BIOS会将USB 3.0端口路由到USB3 xHCI控制器。禁用后,USB 3.0端口将路由到EHCI(USB 2.0)端口。措词“预引导模式”表示此选项仅在引导完整的操作系统之前影响环境(相关的BIOS帮助文本明确提到此选项用于MSDOS中的USB3支持);但是,这似乎也可能影响post-boot环境,甚至在加载Linux之后(将端口以USB2速度运行)也可能具有将USB 3.0端口连接到USB 2.0控制器的效果。
我进入BIOS并在高级设置下找到并将USB 3.0从XHCI启用更改为禁用,并且USB 2(我认为是EHCI)还有另一种设置从启用更改为禁用,或者相反,对不起,我没有记得。无论如何,在重新启动32位Ubuntu 14.04之后,一切正常。
