How to view USB device's VID pid？

The viewing method is as follows:

1. Insert USB into the computer,

2. Right click on "This Computer" and select "Management",

3. In the pop-up dialog box, select [Device Manager] and select [Corresponding USB Device],

4. Right click on the corresponding USB device, select Properties, select Details in the pop-up dialog box, and select Hardware ID for Properties.

There are usually two ways to store VID and PID. The first type is the VID and PID of the main control manufacturer, stored in the bootcode of the main control. The second type is the device manufacturer's VID and PID, which are stored in the device firmware of a non-volatile storage device (EEPROM or Flash) outside the main control. When a USB device is connected to a host, if there is a device manufacturer's VID and PID reported to the host in the firmware, the main control manufacturer's VID and PID are ignored. In theory, the VID of a USB storage device should be the VID of the device manufacturer, not the VID of the main control manufacturer, and these two VIDs should be different (except for devices produced by the main control manufacturer themselves).

USB is displayed in hexadecimal on the computer end and in decimal on the Android end:

For example, converting hexadecimal 4B43 to decimal 19267
