[Opensc-devel] Card missing, for a second

[<J.W...@mi...>]

Hi all,

Did anyone see such behavior before?

With a card firm in the reader, firm in a laptop, PKCS11_eventmanager sometimes (erroneously) reports the card getting missing and found again.
In my case, the consequences are bad, as the "card-out"-event causes my openvpn- connection to be closed.

To make the situation more troublesome: it only happens with a new cardreader I received for evaluation. - not with others-
Could this have anything to do with or not supporting supporting extended APDU's ?

And getting even obscure: if I setup my VPN-connection, and only do constantly a PING, the tunnel stays stable for hours. However, when I run a Citrix-session through it, 9 out of 10 times, my smartcard gets immediately missing for a fraction of time. Bizarre!

For a moment I'd considered that USB-forwarding to be active, and stealing the reader from my linux-system, but I made sure that is not the case.

HtH, Hans
