ST Link Utility is unable to detect the board. STN32f407vgt6. It throws No ST - Link detected. I have Windows 8.1, Keil u5, and latest ST -Link STSW LINK004 DOWNLOADED AS WELL. Even Disk Manager methods did not work. Tried hard for that. Pls do help.

Try a different cable, and USB port.

Keil and ST-LINK Utilities cannot use the pod concurrently. Close Keil to test this.​
