Hello, I started to use UDOO in headless mode and did not bother till today to connect any USB device to it. When I finally did it then it appeared that USB devices do to get power. I first noticed that connecting an USB device does not come up into list of lsusb. Then I connected a mouse what should light up a LED when connected but it did not light up. I am powering my board with a 12V 2A power supply. Any help is appriciated including advice how to proceed if this happens to be a symptom of defective board.
