If you're going to use g_file_storage with dummy_hcd, you should configure the kernel to use dummy_hcd and not net2280. The kernel's build system is set up to expect only one gadget device controller module. When you compiled dummy_hcd by hand it probably was not built correctly. For instance, did set set CONFIG_USB_DUMMY_HCD? You're better off using the kernel build system as it was meant to be used. Configure everything for dummy_hcd instead of net2280.
