First part of the debug output shows only g_webcam and fsl_usb2_udc binding process. The USB cord is not plugged into my PC. As shown by: [fsl_pullup]: PULLUP OFF (this is one of my printks in fsl_udc_core) enumeration shouldn't start, but as you can see in the second part or the debug output, as soon as I plug the USB cord into my PC, enumeration process starts. I'm running _NO_ user-space program, so I'm not worried about " g_webcam gadget: setup complete --> -108, 0/0" (I'll be worried about this later, because when running my user-space program I get a similar problem).
