我正在尝试从运行 Android 4.4.2 的三星 Galaxy S3 手机传输文件。我已经安装libmtp了许多其他与 mtp 相关的软件包，但 Elementary OS 就是检测不到手机。事实上，每当我连接手机时，eOS 都会认为手机是以太网连接（可能是 USB 上的以太网）。
我尝试将 UART 连接从 PDA 更改为 MODEM，但不起作用。我尝试在设备上启用开发人员调试。但同样不起作用。
当我连接设备时，我看到文件中显示以下内容/var/log/syslog：

从外观上看，我的笔记本电脑没有将手机视为 MTP 设备，即使手机确实使用 MTP。
目前，我一直使用无线传输文件，但事实证明这很慢。另外，我必须保持屏幕打开，否则手机将断开与 WiFi 的连接。
那么有没有什么方法可以通过 USB 将手机连接到笔记本电脑以传输文件？
