i think it need usb driver for discovery baord.

Ok, so could you not locate one via a simple Google or Bing search?

Or in a tool chain directory like \Keil\ARM\STLink which has drivers and firmware updates.

Thanks Ahmed, that helped me too.

To give some more info to people with that problem:

You need to plug in the ST-Link (in my case it is an STM32F0 Discovery board), then go to Device Manager (the picture above) - Action - Search for new hardware (or so, I translated this from my windows version). The rest runs automatically.

Maybe the problem results from first plugging in the ST Link (which leads to a failed driver install by windows) and the installing the driver with the file st-link_v2_usbdriver.exe, so maybe there is no problem when you first install the driver.

Thanks again
