Test the model of the main control chip with ChipGenius, and then read the advertising language. The following is the master control corresponding to Kingston slogan, which is not complete. The master control of your USB flash drive is generally SK62 1 1BB. I originally bought documents that are easy to lose after mass production, so I returned them. I hope this will help you ~qq3437640 1 1
