所以它过去只是起作用。插入手机，弹出显示文件的文件夹。后来有一天没有。那是大约两个月前。这很可能是由于对debian的一些更新。我已经到了一个死胡同，想弄清楚这一点，需要一些帮助。
现在我插上电话，看到两个不同的弹出消息框中的一个或多个显示此文本。
Unable to mount SAMSUNG Android SGH I747
Unable to open MTP device '[usb:001,040]'
Unable to mount SAMSUNG Android SGH I747

[顺便说一下，上面的方框中的着色都是错误的。我该怎么阻止？]
我刚从debian repo安装了gmtp应用程序，它有时可以工作。
当我从一个shell启动gmtp时，它会在我单击“connect”按钮后写入此文本。
libusb couldn't open USB device /dev/bus/usb/002/003: Permission denied.
libusb requires write access to USB device nodes.
Device 0 (VID=04e8 and PID=6860) is a Samsung Galaxy models (MTP).
然后在大约10秒后（有时），gmtp连接并在没有更多消息的情况下工作。如果gmtp不起作用，它就会挂起。杀死gmtp后，需要重新启动debian以使手机重新连接。
当我不使用gmtp并且插上电话时，我在dmesg中得到这个：
[692137.131777] usb 1-1.1: new high-speed USB device number 46 using ehci-pci

然后设备出现在尼莫。当我单击它来挂载它时，dmesg中有：

如有任何建议，将不胜感激。
最佳答案
此消息的原因可以是：
可能是由于端口或电缆故障造成的硬件连接问题。尝试使用不同的电缆一次，因为当涉及到硬件时，Message recipient disconnected from message bus without replying会出现。
MTP库问题：有时操作系统更新与旧的MTP库崩溃。试试usb 1-1.1: usbfs: process 11924 (pool) did not claim interface 0 before use。与其删除，不如保留备份，这样如果不起作用，您可以回滚此解决方案。在我的例子中重命名/删除lib是可行的。
