[Ramachandran1992]

Hi team, 
I am doing experiment with NUCLEO-F439ZI board. after some time the LD4 "LED" was not glow. after I unplug the USB cable and reconnect the windows shows the flowing  error

"Power surge on the USB port – Unknown USB Device needs more power than the port can supply. 

A USB device has malfunctioned and exceeded the power limits of its hub port. You should disconnect the device."

The device also not shown in the device manager, none of the LED was not glow. I don't the what is the error happened in the board. Lets I know what is happen to my board and how to recover my board.
Thank you
regards

Hi Ramachandran,

The message told you that the PC can not provide enough power for the board. Normally single nucleo-144 board won't consume a lot of power, I wonder whether you have other daughter board on this nucleo.

You also can try to power the board with other way, such as power the board through user USB port (CN13) and check if the error message is still happened on STlink port.
