我正在尝试通过 mtp 将一部新的 nexus 5x 手机安装到我的笔记本电脑上。当我将其插入时，nautilus 将其识别为 nexus 5x，左侧会出现一个选项。但是，当我单击它时，文件正常显示的区域是空白的，尽管那里应该有文件，而且我无法创建文件。有趣的是，lsusb 返回：
Bus 004 Device 002: ID 8087:8000 Intel Corp.
Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 002: ID 8087:8008 Intel Corp.
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 5986:055c Acer, Inc
Bus 001 Device 002: ID 0cf3:3004 Atheros Communications, Inc.
Bus 001 Device 023: ID 18d1:4ee1 Google Inc. Nexus 4
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
奇怪的是，lsusb 认为它是 nexus 4，而 nautilus 正确地看到了 5x。也许它还不受支持？我在系统日志中发现以下内容：

我在 Eurocom Electra 2 上使用 Ubuntu 15.04。
另外，有比我更有名望的人可以创建 nexus-5x 标签吗？ 谢谢@KGIII
编辑：我尝试使用 mtpfs 进行挂载；错误与我在日志中看到的类似，并且挂载没有发生。

我也尝试从源代码下载最新的 libmtp，但它似乎仍然不起作用——我说似乎因为我不完全确定会发生什么。我尝试了 mtp-files：
libmtp version: 1.1.10
Device 0 (VID=18d1 and PID=4ee1) is a Google Inc (for LG Electronics/Samsung) Nexus 4/5/7/10 (MTP).

OK.
答案1
事实上，它正在起作用！
当您将 N5X（屏幕解锁）连接到 Linux 机器时，N5X 将默认使用 USB 充电（我认为是一种安全功能）。N5X 将出现在您的 Linux 文件管理器中，但不会显示内部存储。如果您下拉 N5X 上的通知栏，您应该会看到它显示 USB 充电。如果您选择它，您应该会获得其他选项，包括用于文件传输的 MTP、用于照片传输的 PTP 和 MIDI。
感谢 davharuk。
编辑 我绝对同意这些评论。完全令人困惑。我也是。
