我的Windows 8也遇到了同样的问题。Android/SDK USB驱动程序安装正确，但我忘记从我的手机安装USB驱动程序。安装手机USB驱动后，ADB工作正常。

我希望这能有所帮助。

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。

我有一部摩托罗拉Razr手机，但我很难识别我的设备。 我所做的是:

1 -从命令提示符(作为管理员)-> adb kill-servers

2 -下载摩托罗拉设备管理器这里-> https://motorola-global-portal.custhelp.com/app/answers/detail/a_id/88481

3 -我一直等到安装完成。

4 -从命令提示符(管理员)-> adb设备

我用的是装有安卓10系统的三星手机。它之前检测到，但在我的工厂数据重置Android 10手机后，在Windows 10上停止检测。虽然在Windows 11 PC上正常检测到。

当我深入挖掘一点，在android手机设置内的开发者选项中，有一个名为默认USB配置[设置->开发者选项->默认USB配置]的配置。当我选择那个选项时，出现了几个选项，默认情况下没有一个是被选中的。

我尝试选择一个接一个的选项，当我选择USB系留选项;然后android设备开始检测。

我找到了一个解决方案(针对Windows 7):

将您的Nexus 10连接到PC 进入Windows设备管理器 r单击ADB Interface ->属性 详细信息->硬件id。

你会看到两张这样的记录:

USB \ VID_18D1&PID_4EE2 USB \ VID_18D1&PID_4EE2&MI_01

5打开“android_winusb. zip”文件。inf文件(我有它在“C:\Users\<username>\AppData\Local\Android\ Android -sdk\extras\谷歌\usb_driver”目录)

6在“[谷歌”中创建记录。NTx86]和[谷歌.]NTamd64]使用ADB接口属性中的硬件id:

谷歌Nexus 10 %SingleAdbInterface% = USB_Install, USB\VID_18D1&PID_4EE2 %CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_4EE2&MI_01

7保存文件，更新ADB接口驱动程序，路径显示为“C:\Users\ AppData\Local\Android\ Android -sdk\extras\谷歌\usb_driver”目录

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。
