So on my desk, i have nothing but a computer running Windows XP SP2.

I want to connect a usb connector into my computer, into a component board with an LED.

Then I want to create a program in C# command line that I can turn the light on and off.

I'm told this could more difficult than I'm planning on... But if anyone has ANY ideas on where to start, or tutorials etc, I would be greatly appreciative.

Thanks :)

there a project on Code Project like that
I think your main library is System.IO it used in such tasks
