Uninstall a Windows driver when the hardware is not connected
提问by Julien M
I am developing a Windows C++ application that drives a motor controller that is plugged on USB. This controller relies on Ftdibus drivers and it works fine on my PC. However, on a test computer it used to work but since I messed up with the Ftdi drivers as soon as I plug the controller, I get a BSoD (mentioning Ftdibus). I would like to cleanup the drivers, but:
我正在开发一个 Windows C++ 应用程序，它驱动一个插入 USB 的电机控制器。该控制器依赖于 Ftdibus 驱动程序，它在我的 PC 上运行良好。然而，在测试计算机上它曾经可以工作，但是因为我一插入控制器就搞砸了 Ftdi 驱动程序，我得到了一个 BSoD（提到 Ftdibus）。我想清理驱动程序，但是：
- they do not appear in Windows "uninstall programs"
- I can't right click on the controller in the device manager and chose "uninstall" because I can't plug the controller (BSoD)
- I tried nirsoft toolthat has an option to uninstall devices but it won't work
I'm clueless, how could I clean up that mess?
我一无所知，我怎么能清理那烂摊子？
PS: if anyone has documentation regarding how drivers are bound to an USB port number, I would enjoy reading on the subject
PS：如果有人有关于驱动程序如何绑定到 USB 端口号的文档，我很乐意阅读该主题

If this is Vista and later, the supported method for deleting a driver package is with pnputil:
如果是 Vista 及更高版本，则支持删除驱动程序包的方法是使用 pnputil：
Just deleting the service is sort of a bad idea, that's not the only thing that installing a driver puts in the registry.
只是删除该服务是一个坏主意，这不是安装驱动程序放入注册表的唯一内容。
I missed the second part of your post about how Windows binds drivers to USB devices. There's a nice description of it here:
我错过了您关于 Windows 如何将驱动程序绑定到 USB 设备的帖子的第二部分。这里有一个很好的描述：

How I do it is one of three ways:
我的做法是以下三种方式之一：
Go into Device Manager, select 'view' menu and select the 'Show hidden devices'. Find your device description and select the 'uninstall' menu option. [easy]
You can use the Service Control Manager command line 'SC' to delete the device driver from the registry. You will need to know the installed driver name. [medium]
Manually delete the driver setup in the registry. Using regedit, you can delete the registry entries for the driver. Drivers registry setup lives under 'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services'. Find the driver name key and delete it. [hard]
进入设备管理器，选择“查看”菜单并选择“显示隐藏的设备”。找到您的设备描述并选择“卸载”菜单选项。[简单]
您可以使用服务控制管理器命令行“ SC”从注册表中删除设备驱动程序。您需要知道已安装的驱动程序名称。[中等的]
手动删除注册表中的驱动程序设置。使用 regedit，您可以删除驱动程序的注册表项。驱动程序注册表设置位于“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services”下。找到驱动程序名称键并将其删除。[难的]
