Does anybody know how to control USB pins on a certain USB port? I think it is definately possible in assembler but what about C++ or C#?
I want to be able to use USB battery as a power supply for an LED or something like that. So then a program would power it on and power it off making it flash.
I know it sounds pointless but I need to do it for something awesome.
I also know that it might require a custom driver.
USB is not trivial, so I guess you’ll have some problems (mis)using it. You would be /much/ better off (IMHO) with standard serial ports, which have been used for stuff like that for ages, with plenty of examples available. If you don’t have serial port available on your target machine, you can use USB->Serial interface cable.
That being said, you’ll probably want to take a look @:
