Looking for a simple cheap way to turn on and off multiple usb devices power via a computer program. How can i do this?
I am looking to use my computer to turn on and off usb devices (like a LED light) via a computer program. I know that USB devices have a constant five volts of power to their ports, and that the normal way to turn on or off a device is using a microcontroller board. I've looked into buying such a board, but they are prohibitively expensive for my project (over $30) and require high level programming skills. I know a little Visual Basic programming and that is about it. With usb devices so numerous and cheap, i am sure there must be a very cheap usb device that can be hacked. Ideally, I'd like to be able to have the computer run timed on-off events and remotely control these over the web. Any help would be great.
