gpg-agent has to be restarted after GnuPG SmartCard pulled from reader

[gnupg-users.dirk at o.banes.ch]

Hi Peter,

thanks for you reply but it is now not working at all. Even if my reader
- Ominkey 3121 is listed in you link.

o.k. I removed pcscd and changed the scdaemon.conf to this:
card-timeout 5
#disable-ccid
debug-level basic
log-file /home/dirk/scdaemon.log
debug-ccid-driver
