Hello everyone,

I have problem with my STM32F4 DISCOVERY board. According to spec:
+ Using "Bootloader (USB FS Device in DFU mode)"
- Configure the STM32F4-Discovery board to boot from "System Memory" (boot pins BOOT0:1 / BOOT1:0)
- Set BOOT0 pin to high level: on the male header P2 place   a jumper between BOOT0 pin and VDD pin 
- Set BOOT1(PB2) pin to low level: on the male header P1 place   a jumper between PB2 pin and GND pin        
- Connect a 'USB type A to Mini-B' cable between PC and USB   connector CN1 to power the board.
- Connect a 'USB type A to Micro-B' cable between PC and USB   connector CN5, the board will be detected as USB device.
I did that steps, but I don't see ,,STM Device in DFU mode. I only see the ST-LINK in USB devices. 
Do you have any ideas where could be the problem?

Thank you for your support,
Mateusz
