I have uncommented DISABLE_ON_DEMAND_POWER_ON and DISABLE_AUTO_POWER_ON and pcscd is not calling PowerOn after start. But it happens after starting of winscard application (scriptor for example). As I understand, PowerOn is automatically called after SCardConnect() and it is a mandatory behaviour, because pcscd must obtain ATR to get information about ICC (protocol for example). Is that correct, and there is no kind of way to change this behaviour?
