看起来你必须为此进行一些设备驱动程序级编程。
无论如何，似乎有一种产品可以捕获原始USB数据.....>
http://www.hhdsoftware.com/usbmon.html.My 猜测你将不得不做类似的东西。
另一个想法是，如果Windows
识别它，您可以尝试禁用/启用该设备。我不确定使用什么API，但我的猜测是有一套
的Windows API / DD API可以让你这样做。

Check out if the manufacturer of the USB lamp provides an SDK which allows
turning off the lamp.

Looks like you have to do somekind of device driver level programming for this.
Anyway there seem to be a product that traps raw USB data at
http://www.hhdsoftware.com/usbmon.html.My guess is that you will have to do
something similar.
Another idea is you can try and disable/enable the device, if Windows
recognizes it. I am not sure what API to use, but my guess is that there is a
set of Windows API/DD API which will allow you to do it.
