+    * The STM32L4x2 SoCs need to control the isolation of the USB features
+    from VDDUSB. This is done through the PWR_CR2 bit USV. The STM32L4 HAL
+    in stm32l4xx_ll_pwr.h wrongly checks for the PWR_CR2_PVME1 bit, which
+    is only available on Cat. 3 devices. Replace the check by PWR_CR2_USV.
