USB DFU on STM32F103C8t6

[Behzad]

Hi everyone 
I want to program Stm32F103C8t6 via USB and STM32Cube programmer version 2.10.0. I am using "STM32 smart V2." I pulled up the Boot0 pin and disconnected and connected the USB cable to the board (the board's power comes from the USB, so it resets when the USB gets disconnected and connected ). Still, the Cube programmer can't find any DFU, and the windows  always come up with the message "USB not recognized." 

let me know if you can suggest any solution 
Best regards

Read AN2606, F103 dont have DFU in system. Exist user bootloader on git for this...

Dear @Behzad ,

DFU bootloader is available only on STM32F105/107 lines inside the STM32F1 series . That table is not wrong but is not exhaustive indeed and sorry for the confusion that might be created . Thanks for the valuable feedback 

Ciao

Thanks for the answers, but exist the posibility to update de bootloader (for STM32F103RGT6 in my case) to activate the DFU perfomance? Exist an oficial bootloader from STM32Micoelectronics? How is it that proces,  ...becouse:

a) I doing the conversion of *.dfu file to *.s19 (DFU from STM32 github)

b) and flashing the MCU with STM32Progrmmer (with STM32-Link v2)

...but USB is not recognized and Windows always says:

 

Thanks in advande !!
