让 Windows 完全忘记 MTP 设备
Getting Windows to completely forget a MTP device
我正在努力为数据采集设备添加 MTP（媒体传输协议）支持。我 运行 遇到了一些困难，因为 Windows 积极地 缓存有关此类设备的详细信息 - 我的许多更改没有明显效果，因为 Windows 只使用它的缓存值而不是查询设备。我可以测试这些更改的唯一方法是将设备插入另一台计算机 - 但我已经 运行 离开其他计算机很久了。
那么，我怎样才能 Windows 完全忘记 MTP 设备，并将其视为全新的呢？在设备管理器中卸载设备，然后拔下并重新插入，无法完成工作。我正在 Windows 7 机器上开发，但需要知道其他版本的答案以及我最终需要在所有这些机器上进行测试。
这不是一件容易的事，但可以做到。您将不得不结合使用工具、注册表编辑等。在播放之前，我强烈建议您进行备份。
我首先从一个漂亮的工具开始 USBDeview，您可以使用它来收集信息。找出您的设备并右键单击该设备并选择 打开 INF 文件。在哪里可以找到删除设备所需的所有信息。
接下来转到高级系统设置并打开设备管理器。菜单 View -> select -> 并勾选 show hidden devices
如果您发现您的设备处于隐藏状态，您可以尝试将其卸载。这可能是您要搜索的缓存。
例如，我在不同的地方找到了我的两个 MTP 设备。一个直接位于 通用串行总线控制器 部分，第二个位于 通用串行总线设备 。所以你可以选择。
如果您想通过脚本自动移除隐藏设备 - 您可以运行以下PS脚本（在blog找到）；（致谢Alexander Boersc 和 trententtye) - 请阅读脚本的示例部分以查找示例：
.SYNOPSIS
Removes ghost devices from your system
.DESCRIPTION
This script will remove ghost devices from your system. These are devices that are present but have a "InstallState" as false. These devices are typically shown as 'faded'
in Device Manager, when you select "Show hidden and devices" from the view menu. This script has been tested on Windows 2008 R2 SP2 with PowerShell 3.0, 5.1 and Server 2012R2
with Powershell 4.0. There is no warranty with this script. Please use cautiously as removing devices is a destructive process without an undo.
.PARAMETER filterByFriendlyName
This parameter will exclude devices that match the partial name provided. This paramater needs to be specified in an array format for all the friendly names you want to be excluded from removal.
"Intel" will match "Intel(R) Xeon(R) CPU E5-2680 0 @ 2.70GHz". "Loop" will match "Microsoft Loopback Adapter".
.PARAMETER filterByClass
This parameter will exclude devices that match the class name provided. This paramater needs to be specified in an array format for all the class names you want to be excluded from removal.
This is an exact string match so "Disk" will not match "DiskDrive".
.PARAMETER listDevicesOnly
listDevicesOnly will output a table of all devices found in this system.
.PARAMETER listGhostDevicesOnly
listGhostDevicesOnly will output a table of all 'ghost' devices found in this system.
.EXAMPLE
Lists all devices
. "removeGhosts.ps1" -listDevicesOnly
.EXAMPLE
Save the list of devices as an object
$Devices = . "removeGhosts.ps1" -listDevicesOnly
.EXAMPLE
Lists all 'ghost' devices
. "removeGhosts.ps1" -listGhostDevicesOnly
.EXAMPLE
Save the list of 'ghost' devices as an object
$ghostDevices = . "removeGhosts.ps1" -listGhostDevicesOnly
.EXAMPLE
Remove all ghost devices EXCEPT any devices that have "Intel" or "Citrix" in their friendly name
. "removeGhosts.ps1" -filterByFriendlyName @("Intel","Citrix")
.EXAMPLE
Remove all ghost devices EXCEPT any devices that are apart of the classes "LegacyDriver" or "Processor"
. "removeGhosts.ps1" -filterByClass @("LegacyDriver","Processor")
.EXAMPLE
Remove all ghost devices EXCEPT for devices with a friendly name of "Intel" or "Citrix" or with a class of "LegacyDriver" or "Processor"
. "removeGhosts.ps1" -filterByClass @("LegacyDriver","Processor") -filterByFriendlyName @("Intel","Citrix")
.NOTES
Permission level has not been tested. It is assumed you will need to have sufficient rights to uninstall devices from device manager for this script to run properly.

删除所有隐藏设备后。您现在可以在注册表中搜索由 ClassGUID= 提供的字符串（没有大括号）并删除注册表中的所有字符串并按照 inf 文件中的其余信息查找任何剩菜。
编辑 - 修复了设备管理器 + 添加了有关 Device Manager (Win10) 的详细信息
上面 "uninstalling it" 的意思是在隐藏状态下卸载它（我不确定我们是否正确理解了彼此 -> 所以我添加信息）：
这是正常连接时的样子：
与 windows 断开连接（但仍通过 USB 数据线连接）：
与 USB 端口断开连接（注意灰色图标）- 这是我认为最好尝试卸载它的时候：

删除所有隐藏设备后。您现在可以在注册表中搜索由 ClassGUID= 提供的字符串（没有大括号）并删除注册表中的所有字符串并按照 inf 文件中的其余信息查找任何剩菜。
编辑 - 修复了设备管理器 + 添加了有关 Device Manager (Win10) 的详细信息
上面 "uninstalling it" 的意思是在隐藏状态下卸载它（我不确定我们是否正确理解了彼此 -> 所以我添加信息）：
这是正常连接时的样子：
与 windows 断开连接（但仍通过 USB 数据线连接）：
与 USB 端口断开连接（注意灰色图标）- 这是我认为最好尝试卸载它的时候：
