Authentic device. Tried a different PC and cable to no avail. Rebooted many times. Issue persisted. Direct connection without docking station or hub. The latest firmware. Thanks.

Windows flagged it as 'Device cannot start'. So I uninstalled the driver and reinstalled it. The issue persisted.

I cannot set up Putty to work with STM32F4. I can accessing the board through st-link from IDE. But the driver doesn't show up under Ports (COM & LPT) in windows Device Manager. I manually added the driver "STLINK Virtual COM Port". Doesn't work. Help!!
