Google Nexus 5 is not being detected by computer/doesn't appear in device manager
提问by user3658385
I have connected my mobile to my laptop via a USB cable, have turned on developer mode, debugging mode, MTP, and installed the google driver via the Eclipse "extras" folder in the SDK Manager. I have unplugged and replugged the device into every USB port on my computer, and am about to restart the PC as soon as I post this question.
我已经通过 USB 电缆将我的手机连接到我的笔记本电脑，打开了开发者模式、调试模式、MTP，并通过 SDK 管理器中的 Eclipse“extras”文件夹安装了谷歌驱动程序。我已将设备拔出并重新插入计算机上的每个 USB 端口，并且在我发布此问题后立即重新启动 PC。
However, given this too will not work, does anyone know how I can get my device to be detected without factory resetting? It's a friend's phone, so I can't have all his files wiped.
但是，鉴于这也行不通，有谁知道如何在不重置出厂设置的情况下检测到我的设备？这是朋友的电话，所以我不能擦除他的所有文件。
All help appreciated.
所有帮助表示赞赏。

I had the same problem after installing the driver, one answer from this question solved my problem What USB driver should we use for the Nexus 5?
安装驱动程序后我遇到了同样的问题，这个问题的一个答案解决了我的问题 我们应该为 Nexus 5 使用什么 USB 驱动程序？
To get my nexus 5 recognized I changed the usb connection mode from MTP to PTP
为了让我的 nexus 5 被识别，我将 USB 连接模式从 MTP 更改为 PTP
Unplug the device from the computer Go to Settings -> Storage. In the ActionBar, click the option menu and choose "USB computer connection". Check "Camera (PTP)" connection. Plug the device and you should have a popup on the device allowing you to accept the computer's incoming connection, or something like that. Finally, you should see it now in the DDMS and voilà.
从计算机上拔下设备 转到设置 -> 存储。在操作栏中，单击选项菜单并选择“USB 计算机连接”。检查“相机（PTP）”连接。插入设备，您应该在设备上有一个弹出窗口，允许您接受计算机的传入连接，或类似的东西。最后，您现在应该在 DDMS 中看到它，瞧。

Solution is to open Android SDK Manager and download/install latest USB drivers (under Extras). Then in Windows Device Manager (devmgmt.msc), right click the Nexus 5 device and select Update Driver Software. Then, Browse my computer for driver software > Android SDK Dir > Extras > usb_driver
解决方案是打开 Android SDK Manager 并下载/安装最新的 USB 驱动程序（在 Extras 下）。然后在 Windows 设备管理器 (devmgmt.msc) 中，右键单击 Nexus 5 设备并选择更新驱动程序软件。然后，浏览我的计算机以查找驱动程序软件 > Android SDK Dir > Extras > usb_driver

You are using windows I guess. If yes go to device manager remove your old driver. It may be listed as Android phone or nexus. Then reconnect it. This solved my problem.
我猜你正在使用窗户。如果是，请转到设备管理器删除旧驱动程序。它可能被列为Android 手机或nexus。然后重新连接。这解决了我的问题。
