Dear Members Our company is designing a battery powered device that uses a USB port to update firmware. This port cannot be used to provide 5VDC to charge or power external devices as we won't be providing those connections. (to limit battery power) How best should we label this USB port to indicate this port cannot supply power. Is there are special logo anyone is aware? Of course we will mention this in the user manual, but need another method on the product itself to avoid user frustration. Like to hear your thoughts. Kind Regards, Ryan Jazz
