Hello,

I read stm documentation on how to enter a microcontroller into dfu mode Iam using stm32f105, and below are the steps that i did 1- Boot0=1, Boot1= 0 2-PD6 = PA10 = PB5 = 0 3- make reset 4- connect the board to computer via usb cable But the computer doesn't recognise the board. Is there anything that i have to do in order to let the board be recognised by the computer as usb device in order to install the correct drive to use dfuse? Is there any program that the microcontroller should be programmed with before doing this step other than the one comes in system memory(bootloader)? Please share your ideas on how to enter a microcontroller in dfu mode

Yeah, pretty sure you need to install the ST DFU software first to install a driver for the default VID/PID
