Point 2.2.2 sounds promising:
- Workaround
Apply the following sequence before entering Standby mode:
1. Disable all used wakeup sources.
2. Clear all related wakeup flags.
3. Re-enable all used wakeup sources.
4. Enter Standby mode.
Note: When applying this measure, if one of the wakeup sources is still kept high, be aware that the microcontroller
enters Standby mode but then wakes up immediately, generating the power reset.

Workaround works.
As described in the stm32 errata, the device can not be powered off when usb is connected (WKUP2 stays high).
This is ok when USB-Mode is implemented and just showing battery capacity.
