Hi, Yes, I agree with that, both the Host and device can't access the backing storage at the same time. The device should access the backing storage only after unloading the file storage gadget module. > The only way to be sure that the copy is complete is to wait for the > gadget to be unplugged from the host. The device is bus powered and it has very limited flash to store kernel image and configuration information.
