[rohitsam]

The datasheet of stm32f411 says it supports USB DFU bootloader, but Im unable to programe Stm32f411-disco board via USB with internal DFU on Cube programmer, I have connected the boot0 to vdd and using the USB connected to PA11\PA12 for DFU.

Is there any specific hardware change that I have have this working?

Thank you.
