I forgot to mention ... I had to save the .c/.h files to another subdir -> delete the entire Project -> Create a new Project -> move the .c/.h files back into the project. Without those actions, Code Composer 4 was unable to find the USB connection.
BTW I checked Code Composer 5 ... it displays only three USB ports, even though there are six. It appears to re-assign one of those three to one of the USB ports on the front of the PC. It would be good if the Code Composer code writers fixed this.
Code Composer should display all six USB's and provide info about those six. I have another program that displays all six and indicates what is attached to them ... see attachment.
