对于Windows，只要结束所有与Blue堆栈相关的进程或任何类似的模拟器(如果您正在使用)。

为我工作。

如果你为Nexus启用了开发者选项和USB调试，win-usb应该可以工作。

你的驱动程序是否正确的一个标志是它在设备管理器中的名称中是否包含ADB。

对于我的Galaxy系列，我安装了一个驱动程序，但不是ADB驱动程序。

对于许多非nexus安卓系统，win-usb驱动程序将无法工作。相反，您需要安装一个OEM驱动程序:https://developer.android.com/studio/run/oem-usb.html

这最终让我得到了一个ADB兼容的驱动程序，在切换到PTP后，ADB终于能够找到我的设备。

可能有两个原因导致adb devices命令不适合您。你手机的USB驱动程序没有正确安装，或者你没有启用USB调试模式。

我创建了一个工具，使安装USB驱动程序一个点击的事情。

只需将您的手机以USB调试模式连接到PC。 运行我的工具

它将检测并安装特定于您的手机的驱动程序，并安装最新的ADB和Fastboot二进制文件。

For the Blu Studio 5.5s ADB drivers, you have to go through this hoop. I am certain it is the same with all Blu phones or maybe for all non-Google mfg phones, I am not sure. First of all if you connect the Blu device with USB cable and USB Debuggin off, you will see that Windows 7 loads a generic driver for you to copy on/off files to the phone and SD storage. This will appear when the USB cable is first plugged in and appears as a device icon under Control Panel, Device Manager, Portable Devices, BLU STUDIO 5.5 S (or the device you are working with). Do not bother getting the hardware ID yet - just observe that this happens (which indicates you are good so far and don't have a bad cable or something).

Go to the phone and switch on USB Debugging in the Developer section of your phone. Notice that an additional item appears as an undefined device now in the device manager list, it will have the yellow exclamation mark and it may have the same name of the phone listed as you saw under Portable Devices. Ignore this item for the moment. Now, without doing anything to the phone (it should be already in USB debug mode) go back to the Portable Devices in Device Manager and right-click the BLU STUDIO 5.5 S or whatever phone you are working with that is listed there without the exclamation mark (listed under Portable Devices). Right click on the icon under Portable Devices, in this example the name that appears is BLU STUDIO 5.5 S. On that icon select Properties, Details, and under the pull down, select Hardware IDs and copy down what you see.

对于BLU STUDIO 5.5 S，我得到:

USB\VID_0BB4&PID_0C02&REV_0216&MI_00
USB\VID_0BB4&PID_0C02&MI_00

(注意，如果你不按顺序这样做，HW ID将与手机USB调试关闭时不同。你想复制的值，它改变时，USB调试是ON)

现在按照上面的说明进行操作，当然要定制添加INF文件的行，使用与您自己的手机相关的行，而不是与Nexus 10相关的行。下面是要定制的内容;当你下载SDK时，你应该有一个从ZIP扩展而来的文件结构，如下所示:

\adt-bundle-windows-x86_64-20140321\sdk\extras\google\usb_driver

找到名为android_winusb的文件。usb_driver文件夹中的Inf 复制它并命名为任何名称，比如myname.inf 编辑myname。Inf和添加行如上所述，只修改为您的特定电话。例如，对于BLU STUDIO 5.5 S，我根据提示在2个位置添加了以下2行。

;BLU STUDIO 5.5 S
%SingleAdbInterface%        = USB_Install, USB\VID_0BB4&PID_0C02&REV_0216&MI_00
%CompositeAdbInterface%     = USB_Install, USB\VID_0BB4&PID_0C02&MI_00

请注意，您将这些行添加到32位和64位部分中，以与教程中的示例相匹配。

Now go back up to the unknown device that appeared in Device Manager when you switched on device USB debugging and right click on this item (has yellow exclamation mark), right click on it and then select Update Driver Software, and then Browse My Computer, Let Me Pick, click on the Have Disk button and browse to find the myname.inf. Continue to agree to all the prompts warning you it might not be the right driver. As the final step, Windows should have identified the device as Android ADB Interface and once that is done, you should be able to go back, open your CMD window and run the command "adb devices" as instructed in this tutorial and now you should see that the phone is now discovered and communicating.

现在您可以开始使用adb命令了。

你最近更新了安卓系统吗?我更新到棒棒糖，突然间我没有了adb设备。嘘!我花了一段时间尝试了几件事，但都无济于事。然后我进入我的开发人员选项，你瞧，“USB调试”被关闭了。愚蠢的谷歌。在把它重新打开后，它立即显示出来，我又开始工作了!

进入设备管理器，检查硬件id。 检查usb。Inf文件中列出了设备 如果不是，添加设备硬件id并从设备管理器中安装它。
