我已通过USB电缆连接我的移动到我的笔记本电脑，打开了开发人员模式，调试模式，MTP，并通过安装在SDK管理器Eclipse的额外文件夹中的谷歌驱动程序。我拔出并重新插入设备进入我的电脑上的每个USB端口，我要，只要我发布了这个问题重新启动电脑。

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.

不过，鉴于这也将无法正常工作，没有人知道我能得到我的设备没有出厂重置被检测到？这是一个朋友的电话，所以我不能让他的所有的文件擦除。

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.

所有帮助AP preciated。

All help appreciated.

从计算机上拔下设备 进入设置 - >存储。 在动作条，点击选项菜单中，选择USB连接电脑。 检查相机（PTP）的连接。 将设备，你应该有设备，让您接受计算机的传入连接，或类似的东西上弹出。 最后，您现在应该看到它的DDMS就万事大吉了。

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.
