1, there are many brands of USB flash drives, and the chips used by the same brand are different, so we must first find out the master control used by USB flash drives, and then find the mass production tools corresponding to the master control. ChipGenius is recommended for chip inspection tools. As for why it is used, we will talk about it later.

2. After downloading and installing the chip wizard from the Internet, insert the USB flash drive to be repaired into the computer. It is recommended to plug it into the USB2.0 socket (the inside of the USB3.0 socket is blue). After computer identification, open ChipGenius, and the software will automatically identify the USB flash drive and display the current USB device list. At present, I only inserted 1 USB flash drive, as shown below.

3. After clicking the USB flash drive, some information about the USB flash drive will be displayed in the following window. Find the master project and write down the name and model of the master. Here we know:

Main manufacturer: Chip Bank (Xinbang)

Main control model: CBM 2093 (V88)-[2009-03-28], as shown below.

The second step is to find the tools for mass production.
