I'm trying to make the USB_FS interface to work on my F746G Discovery board. I decided to try the "AUDIO_Standalone" in the "USB_Device" folder. This project builds and runs fine under System Workbench after adding proper source and include paths in the project settings. A led is blinking in the main loop after all initialization in order to confirm the program is running. However nothing is listed when connecting the USB_FS (CN13 micro-usb connector) to the PC. Nothing is listed with the "lsusb" in linux and under windows nothing appears when connecting. I've tried both Windows 7 and Windows XP. I assume something must be listed in the operating system in order to be able to stream any audio data to the Discovery board.
