You hit the mark! When I change the permissions in /dev/bus/usb/001/005,
GnuPG works fine with my cardreader - even as normal user.

Do you have incidentally gnupg-ccid.rules and/or gnupg-ccid scripts which
do the job? The ones I have change the permissions in /proc/bus/usb

Thanks a lot for your tip (I googled some days and found nothing
