I plug in the USB, makes connection into MSC disk emulation.
I hold down ISP pin then reset.
USB reconnects and shows firmware.bin file.
I delete firmware.bin and copy my user.bin file to it.
When I unplug the USB cable, sometimes  my user code starts up, sometimes it does not.
Is there anything I can do to guarantee that my code starts up.
