I saw an old post that people said VBUS is a must, well, it is not
From the datasheet 30.5 - ''The VBUS pin can be freed by disabling the VBUS sensing option. This is done by setting the NOVBUSSENS bit in the OTG_FS_GCCFG register. In this case the VBUS is considered internally to be always at VBUS valid level (5 V).'' It applies to HS as well (different register though) #vbus
