[Opensc-devel] smart card reset after 5 seconds on Windows

[Vincent Le T. <vin...@my...>]

Hi,

I just want to share something on which I've lost my day before finding
this:
Since Windows 10 (8?) the card is reset if a smart card transaction is
inactive for 5 seconds.

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."

This timeout was not active on Windows 7.
Not easy to attach a debugger to debug OpenSC with that  ...

regards,
