问题描述
问题： 华硕的Nexus 7无法识别由亚洲开发银行如果正确安装和连接
Problem: Asus Nexus 7 not recognized by adb when correctly installed and connected
设置： 华硕的Nexus 7平板电脑 Windows 7的64位操作系统
Setup: Asus Nexus 7 tablet Windows 7 64 bit OS
取步骤：
- 在安装64位Java JDK（http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html）
- 在安装Android的SDK（http://developer.android.com/sdk/index.html）
- 在安装谷歌的USB驱动程序（http://developer.android.com/tools/extras/oem-usb.html）
- 设置平板电脑的USB调试模式
在Windows设备管理器中，Nexus是公认的通过Android的复合亚行界面的Android设备。设备状态显示已连接和工作正常，从谷歌运行驱动程序7.0.0.1版本（12年8月27日更新）。
In the Windows Device Manager, the Nexus is recognized as an Android Device via Android Composite ADB Interface. The device status indicates it is connected and working properly, running driver version 7.0.0.1 (8/27/12 update) from Google.
然而，当我在命令提示符下运行 ADB设备（在SDK /平台工具目录下），Nexus的不来了作为一个连接的设备 - 的列表是空的。
However, when I run adb devices at the command prompt (in the sdk/platform-tools directory), the Nexus does not come up as an attached device - the list is empty.
有没有人有什么问题可能是任何见解？我试图卸载并重新安装所有驱动程序，每次重新启动计算机。我已经尝试了各种USB端口和电缆，以及没有成功MTP和PTP连接之间进行切换。
Does anyone have any insight on what the problem might be? I have tried uninstalling and reinstalling all drivers, restarting the computer each time. I have tried a variety of usb ports and cables, as well as switching between MTP and PTP connections with no success.

试试这个（从上述源引）
Try this (as quoted from the above source)
在了Nexus 7是否插有一个持续的通知 表示CONNECT AS /媒体设备（MTP）。在这种状态下ADB设备 不会显示了Nexus。不完全是显而易见的，为什么，但我选择了 第二个选项相机（PTP）的设备可用于调试。 这种选择是持久的，而我猜，用带新 设备，直到告知，否则它会连接为MTP
When the Nexus 7 is plugged in there is a persistent notification that indicates "CONNECT AS / Media Device (MTP)". In this state adb devices will not show the Nexus. Not exactly obvious why, but I you select the second option "Camera (PTP)" the device is available for debugging. This choice is persistent, and I'm guessing that with a band new device it will connect as MTP until told otherwise
