I just recently bought my first arduino which has worked without any difficulty until now. When i connect the arduino through USB the "on" LED just blinks a couple of times while plugging in and then it stays low --> no power on my arduino. Also, i noticed that the small chip next to the usb port with the label "1505" gets really hot. I don't know if it that has anything to do with the usb problem.
Anybody know what the problem could be? do i have to buy a new arduino?
Thanks in advance! :)
