The driver actually returns "0" upon IFDHPowerICC which means "ok". That's why 
IFDHSetProtcol() isn't called (because all readers I worked with so far 
returned an error if the card couldn't be connected at this point, due to a 
false protocol etc, see my explanation for the Kobil reader).

@Ludovic: If I understand you correctly IFDHSetProtocol must be set anyway? So 
maybe its just as easy as calling this function (we already try to extract 
the protocol from the ATR but so far the result isn't used).

Martin
