I created with USB wizard project for my FM4-176L-S6E2GM Pioneer Kit, compiled with Keil. I am getting an error message when connecting with Cypress Serial Port Viewer: "The Port could not be opened. A device attached to the system is not functioning". Similar text with other terminal programs. I have latest Bios, well working Windows 10, latest drivers, board USB driver from a created project, no problems with other USB devices. Looks like Windows driver problem?
But on my other PC, this project is working well.
On both when loading project I am getting from Keil message:
*** error 6: missing string terminator
Is this important message? I have no idea, where to find this error source
