How to handle USB flash drive write protection and query USB flash drive ID information

Some time ago, after plugging and removing your USB flash drive on a TV, it was required to be formatted again. This may be because the unscrupulous program on the TV deleted the key configuration information of the USB flash drive. After formatting the USB flash drive, the USB flash drive is prompted to be write-protected. However, my USB flash drive does not have a write-protection physical switch, and I have tried many methods on the Internet without any changes. In the end, I can only perform mass production operations on the USB flash drive.

First, use the chipgenius software to query the USB flash disk information,

Second, find the corresponding manufacturer's production tools based on the U disk chip information. My USB flash drive model is gl811. The production procedure is as follows:

After mass production, the data can be formatted normally.

In addition, a recent project survey requires a unique identifier of a USB flash drive. The USB flash drive has its own physical and logical serial numbers. However, in fact, both serial numbers can be tampered with manually. Therefore, if you need to obtain the unique identifier of the USB flash drive for information security and copyright protection, you must combine multiple USB flash drive parameters to build a unique identifier, such as PID or vid.
