I have a battery-powered device which may connect to a USB host or a charger.
How can I tell if the device is currently connected to a charger or a Host in Suspend mode?Thanks,Boaz #stm32 #usb

Hi
Most chargers do not have a micro controller which will initiate USB comms. So, if you get power and there is no USB traffic, then it is likely to be a dumb charger.
