Sounds like a call to SCardStatus resets the 5 second timer. Could
a thread be added with a 2 second timer to to keep the transaction
alive? May not help with debugging.<br>

<div>Hi,<br>
<br>
</div>
I just want to share something on which I've lost my
day before finding this:<br>
</div>
Since Windows 10 (8?) the card is reset if a smart
card transaction is inactive for 5 seconds.<br>
<br>
</div>
Quote: "If a transaction is held on the card for more
than five seconds with no operations happening on that
card, then the card is reset. Calling any of the Smart
Card and Reader Access Functions or Direct Card Access
Functions on the card that is transacted results in the
timer being reset to continue allowing the transaction
to be used."

<div>This timeout was not active on Windows 7.<br>

<div>Not easy to attach a debugger to debug
OpenSC with that ...<br>
