The only way to be sure that the copy is complete is to wait for the gadget to be unplugged from the host. Remember also that the gadget MUST NOT mount the filesystem in the RAM partition while it is connected to a host. The USB mass storage protocol is not meant for file sharing; if CPU on the gadget and the CPU on the host try to access the files on the backing storage at the same time, the filesystem will get corrupted.
