I yesterday hooked up the stk500 development board through usb-to-serial adapter to my acer laptop running windows 10. It was working okay throughout the day. Today when I turned it on, none of the USB port seems to be working. I mean it wouldn't detect any device. A flash drive or the adapter whatsoever. The Device Manager shows that all the devices listed under the Universal Serial Bus list are working properly, yet nothing is getting detected. I have restarted system a few times, started in safe mode, nothing! So it leads me to the question: Could my USB ports be fried due to excess current drawn by the dev board. Is it possible? I just checked through the multimeter for any voltage on the USB port pins but it does not show any power. Has someone run into this issue before. Need help please.
