[pkg-gnupg-maint] Bug#913488: scdaemon: gnupg --card-status does not recognize smart card via usb reader

[Elmar Stellnberger]

Package: scdaemon
Version: 2.1.18-8~deb9u3
Severity: important

Dear Maintainer,

The problem is that gnupg does not recognize my gpg-card if I insert it 
via the Gemalto PC-card reader; if I use the integrated reader it works.
The problem only occurs with Debian GNU Linux 9. The USB reader still 
works well with Debian GNU Linux 8; i.e. this is a regression. It is not 
the way that gnupg always fails to recognize my gpg card via the USB 
reader; sometimes it works; sometimes it does not.

$ gpg --card-status
gpg: selecting openpgp failed: Kein passendes Gerät gefunden
gpg: OpenPGP card not available: Kein passendes Gerät gefunden
