2. To be compliant with the USB 2.0 full-speed electrical specification, the USB_DP (D+) pin should be pulled
up with a 1.5 k
Ω resistor to a 3.0-to-3.6 V voltage range.

3. The STM32F3xxx USB functionality is ensured down to 2.7 V but not the full USB electrical characteristics
which are degraded in the 2.7-to-3.0 V VDD voltage range.
