I have a brand new STM32F407 Discovery board. I have installed Audio Weaver Designer 6.18.02 STMicro.exe.
I have connected up the Discovery board with the USB cable to my PC.
Then I proceed to use Audio Weaver Server --> Target --> Change Connection --> USB (VID: 1155/PID:407) --> Click Change...
A window dialog popped up showing "Unable to create USB port - is this port in use by another program?"
I tried with another PC and changing to a new Discovery board, repeated the installation and I got the same error.
What else can I do? I really don't think the USB port is used by any program at all.
