The U disk that cannot detect the chip model is not able to find the corresponding mass production tool.
1, you can use the high version of the chip wizard to detect the U disk chip model, in some cases because the tool version is too low to detect the U disk's main control chip model.
2, you can open the U disk directly to view the model of the main control chip. Be careful not to damage the hardware of the U disk when you disassemble it, and the U disk that you disassemble will generally not have after-sales service.
