I have an existing usb device that I would like to add led's to. It's not arduino based at all. It looks like its only using 100mA. So I had some questions.
What is the best way to go about adding them? Is that 100mA usage limited by the device's design, such that using more than that would damage it? Or is it set in the usb controller and that's all the computer will deliver to the device?
Basically I have alot to learn and figured this would be the best place to start asking.
