I don't think it is working when you have the usb cable plugged in. You don't see the error because it doesn't really go into suspend mode when the cable is plugged in. You should see something like "core_domain failed to suspend error 1" when you resume from suspend. I found the error to be in musb_core.c, musb_save_context(), when executing this line: musb->context.power = musb_readb(musb_base, MUSB_POWER); I wonder if the memory is suspending before the USB can save the context.
