    I solved my problem. I replace Mass Storage drivers with the WinUSB driver using the Zadig utility.

    Thank you anyway.

    I set OpenOCD debug method and press Detect button, ST-Link V1 successfully detected. When I hit “Test OpenOCD settings” the warning window appearing says “USB mass storage” does not appear to have “ST-Link Driver” driver installed. OpenOCD may have problems finding your device. Try installing it now?” Pressing Yes show me error message “Automatic driver installation failed. Do you want to try installing it manually?” Next attempts wouldn’t help either.

    The device PID&VID is 0483/3744

    Log on debug attempting:
