Thanks for the quick reply.
By using STM32 ST-Link utility V4.2.0.0, I can connect and flash binary to the board.
I also have System Workbench for STM32 AC6 Eclipse based IDE, it works perfectly with the board.
So i don’t think there is any issue with my USB ports.
Will you please provide some hints or redirect to links where I can get to know how to check if some USB virtualization/forwarding software is interfering with ST-Link?
