Shutting down USB device FS to reduce power consumption

Due to power saving I want to disable the USB stack on the fly.

For comparison: If I do not enable the USB stack at all (e.g. by not invoking MX_USB_DEVICE_Init()) everything is fine. If I do and decide to shut it down later during runtime via

void MX_USB_DEVICE_DeInit(void)
{
  USBD_DeInit(&hUsbDeviceFS);
}

I can not get the same power consumption results compared to the first approach where I do not enable the USB stack at all. So there must be something that consumes still power.

Any ideas what I am missing? I am working with an F411 and the HAL V1.3.2.

Any help is appreciated!
