Posted on October 16, 2014 at 20:44I have the code for USB device working. I initialize USB with USBD_Init. My code also needs to turn off USB completely in one mode to minimize power consumption. I tried USBD_DeInit. There was no change in the power consumption. Looking at the source code USBD_DeInit does nothing. Does anyone know how to completely reset the USB hardware back to the default state to turn USB off and minimize power consumption?

USBD_Status USBD_DeInit(USB_OTG_CORE_HANDLE *pdev)
{
/* Software Init */
return USBD_OK;
}
