    problem with connecting the board by usb



      I have a problem with my new Intel Galileo board.

      I have done a circuit with optocoupler CNY70 like at this picture:



      I loaded a simple program to use this sensor. Then I disconnected a cable from A1, because I wanted to connect it with A0  (I noticed, that I set A0 in the program.)

      Then I heard the sound of disconnected usb. Now the usb led on the board not light. I also can't connect the board with my computer, because it isn't visible.

      Is it posible to do a short circuit and demage the board by disconnecting this cable ?

      Does anyone know, what could cause the usb problem on my board ?
