[.net] Enable/Disable USB port
According to this Microsoft KB article, there is a registry key for this.
To disable:
To re-enable:
However, the above code only for mass storage devices, not other devices such as keyboards and mice connected to the USB bus.
To disable:
Registry.LocalMachine.OpenSubKey(@"SYSTEM\CurrentControlSet\Services\USBSTOR", true).SetValue("Start", 4);To re-enable:
Registry.LocalMachine.OpenSubKey(@"SYSTEM\CurrentControlSet\Services\USBSTOR", true).SetValue("Start", 3);However, the above code only for mass storage devices, not other devices such as keyboards and mice connected to the USB bus.
There is no easy way to enable/disable hardware using C# that I know of. I remember because I looked up how to disable the NIC using C# and it required a bunch of complex things to be done. Since I was merely costing out how much it would be to code such a thing, I told my boss that it wasn't worth it. The registry key solution is best if that's what you're trying to do. Otherwise you might be better off using C++/CLI.
There biggest chance is that the solution is there for you through the Win32 API in C. Which means, you'll have to P/Invoke the required functions/structures and then call those functions from your C# application.
It probably doesn't matter much if you write a C DLL that does all this stuff, and then P/Invoke the library's specific function on enabling/disabling the USB port or writing all the code in C#(However, I expect the code to be more simple in C).
Now, the question arises: Why do you want to disable USB ports? If you want to do this on a system scale because of security, why not look into hardware profiles or group policies? These are much more efficient at these things.
