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!!

The driver installation file is stlink-server 2.0.2. MCU is STM32F405RG.

Ok, but what does Windows flag as the actual reason for the exclamation point? Look at the Properties..

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

Is this an authentic device or a clone?

Have you tried a different cable?

Dell, Hub or Docking Station?

Current Firmware?

Does it work on other computers?

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.
