Calling the STM32 SystemMemory Bootloader

I'm trying to launch the SystemMemory Bootloader on a STM32F4 as documented in this video:
The PC detects a new device on USB but it does not enumerate.

Using the Boot0 pin to get into the bootloader works fine, and USB detects the DFU.

I'm using ChibiOS/GCC, but even launching the bootloader before calling halInit() and chSysInit() does not help.

Any idea?
