Modifying USB Devices
I have random devices that are cheap and boring. Many of them are small mp3 players. I want to know if there is a way to get into the mp3 players os when it is connected via USB. I would like to change up some of the icons or just to mess with is. Is there any way to do this? Thank You!
(P.S. None of the mp3 players are made by Apple.)
