The problem is, why here is a "62" (power on) message send from PC to smartcard reader?

This causes the problem occurs in step 6: Connect failed:

Connect error: The smart card annot be accessed because of other connections outstanding.

Whether this is a bug of CCID device driver?

Please help me!

Answer 1

I guess, this is the wake up mechanism of win8 system. Re-establish the connection when wake-up. But the re-established connection handle, is not got by my pcsc tool. How to get it?

Power event is only sent to the device via driver, the application cannot get it. so looks like this is exactly the same behavior as what you see. This is Windows design.
