Problem to connect the STM32F4DISCOVERY with ST-Link

I just receive my STM32F4DISCOVERY. I installed IAR EWARM, and ST-Link driver V2. But after several tests on two laptops, I am unable to link the discovery board with ST-Link.

This is the message displayed: "Fatal error - ST-Link connection error Session aborded!"

And this is the message on ST-Link utility: "No ST-Link detected"

Do you have any idea of what happened? Thanks!
