USB VBUS Voltage Level(STM32F407)

Question asked by Nagano on Feb 18, 2015
I wonder, STM32F4 series can use USB VBUS 5V or not.
In fact, I have been using this device for 4 months with VBUS 5V directly, but it seems no specification of VBUS on DM00037051.pdf

For instance, I'm using like this case USB connector to CPU PA9 port directly.

Nothing any problem long time for me, so It seems OK.
If you know any opinion about this case, please show me the datasheet.

Thank you.
