Does a USB flash drive need the power cables found in a USB extension cable, or does it only need the data cables? Answered
So, I have a project I hope to complete in modifying a tron identity disc. Here is my hopeful setup: A flash drive is hidden inside the disc with a usb power cord extension going from it to the outside world. My hope is to have the 5V of power coming from my computer turn on a set of extra LEDs in the disc, while the data can be accessed and transferred. Does a USB flash drive need the power inputs from a normal USB cord to function?
