Hello,
The error is normal since the card really isn't being powered up. Memory
cards do not all have ATR's and some of them that do don't always follow a
particular pattern. One way you can bypass this is to just return a bogus
ATR such as 3B 00 or just 3B for every memory card that is inserted. The
card service provider which sits on top of PC/SC will then manage
identifying the card.
