关闭电源，USB接口编程 [英] Turn off power to USB Port programmatically

问题描述

我有我工作的一个项目，我想用这些： http://www.woot.com/blog/post / USB供电，活泉关断灯-2

I have a project that I'm working on and I want to use these: http://www.woot.com/blog/post/usb-powered-woot-off-lights-2

不过看起来他们只是有开/关开关。他们不是东西，你可以用编程接口。

However it looks like they just have on/off switches. They aren't something that you can interface with programmatically.

所以，我在想，如果我能找到一种方法来切断电源到USB端口，这将让我把灯打开和关闭我的应用程序。但是我找不到任何方法来切断电源到USB端口。这可能吗？

So I was thinking, if I could find a way to cut the power to the USB port, that would allow me to turn the lights on and off with my app. However I cant find any way to cut the power to the USB port. Is this possible?

推荐答案

如果您有管理员权限，然后运行以下命令：

If you have admin privileges then run the following:

Microsoft.Win32.Registry.SetValue(@"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR", 开始，4，Microsoft.Win32.RegistryValueKind.DWord）;

Microsoft.Win32.Registry.SetValue(@"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR", "Start", 4, Microsoft.Win32.RegistryValueKind.DWord);
