1, if the U disk needs mass production, there is no master chip model, it is unable to find the mass production tool that matches the master, so we must find a way to detect it.
2, detect the U disk master model of the tool software chip wizard and chip worry two, if one of them can not be detected, you can try another.
3, if both can not be detected, it is necessary to find a way to disassemble the U disk shell, find the small square integrated block on the circuit board, it is the main control, generally there will be a brand and model.
4, if you still can't find it, then only download the production tool one by one, until you try to detect the mass production tool of the U disk, in order to mass production.
