STM32F105 DFU BootLoader does not work

[arilink]

I successfully used USB DFU on STM32H7, and I want to perform the same operation on STM32F105. I learned from the manual that the system BootLoader address is 0x1FFFB000. But when I try to jump into USB DFU mode, windows prompts the device descriptor but my users The program can use USB to communicate normally. What is the problem?

Please refer to this post and FAQ: DFU mode with system bootloader is not working, while USB does, that may answer your question.
