Ubuntu 识别了该设备，并似乎在本例中将其分配给了 sdc，但 mount 一直返回“未找到介质”消息。lsusb输出如下：

最后我的mount呼吁是：
sudo mount /dev/sdc /mnt
mount: no medium found on /dev/sdc
我重启了好几次，用完了电脑上所有可用的端口。手机型号是索尼爱立信。我还创建了 udev 规则：
SUBSYSTEM=="usb", ATTR{idVendor}=="0fce", MODE="0666", GROUP="plugdev"。
该文件位于：
/etc/udev/rules.d/51-android.rules。
我是不是太笨了，忽略了一些显而易见的事情（如果真是这样的话，我很抱歉……）？
谢谢你尽你所能的帮助。
更新
由于此设备未激活（Verizon 不提供服务），我无法更新软件。搜索后，似乎无法使用 SuperOneClick 程序（我真的很想使用这个程序……）获取 2.3.4 的 root 权限（因此我可以将最新的固件刷入设备）。因此，我最终通过获取 root 权限并将 2.3.3 固件刷入设备，将设备降级到 2.3.3。重新启动设备后，手机询问我是否要安装 SD 卡，我这样做了，Ubuntu 正确识别了它。因此，我现在可以继续我原来的项目，但如何安装运行 2.3.4 的设备的 SD 卡的原始问题仍然没有答案……因此，对于拥有运行 2.3.4 的 Sony Ericsson Xperia Play 并尝试安装 SD 卡（不取出卡并放入 SD 卡读卡器……）的其他用户，我建议降级（或升级……）设备，直到找到实际解决方案。获取 root 权限需要您自担风险！
答案1
您无法像闪存驱动器那样以正常方式安装 Android 设备。
您必须使用 MTP（媒体传输协议）——一种用于智能存储设备的协议。有一个名为中期规划框架您可以以此方式使用它。更多信息请参见此处：在 Ubuntu 上安装 MTP Android 的 SD 卡。
我还发现了这个关于如何使用 Go-MTPFS 在 Ubuntu 中正确安装 Android 4.0+ 设备这可能会有所帮助。本主题中的想法是关于使用去mtpfs。
