Another issue here is that you likely need to turn off "connect as media device" to be able to connect with adb.

这里的另一个问题是您可能需要关闭“作为媒体设备连接”才能与 adb 连接。

I had this problem suddenly crop up in Windows 7 with my Nexus One - somehow the USB drivers had been uninstalled. I ran android-sdk/SDK Manager.exe, checked Extras/Google USB Driver and installed it. Then I unplugged the phone and plugged it back in, and ran "adb devices" to confirm the phone was attached.

我的 Nexus One 在 Windows 7 中突然出现了这个问题——不知何故，USB 驱动程序已被卸载。我运行了 android-sdk/SDK Manager.exe，检查了 Extras/Google USB Driver 并安装了它。然后我拔下电话并重新插入，并运行“adb devices”以确认电话已连接。

This doesn't work for all phones, just the ones listed here: http://developer.android.com/sdk/win-usb.html

这不适用于所有手机，仅适用于此处列出的手机：http: //developer.android.com/sdk/win-usb.html
