I have an SCR3310 card reader on an Ubuntu 10.10 system, and installed
the drivers through the libccid package. This works out of the box for
root, but mortal users can't access the card at all. I tried a lightly
modified version of the scripts from
http://www.gnupg.org/howtos/card-howto/en/smartcard-howto-single.html
but without success.
Here's all the debugging info I could think of. Anyone have any
suggestions for getting this working?

# Note that for this script to work, you'll need all of the following:
# a) a line in the file /etc/hotplug/gnupg-ccid.usermap that corresponds
# to the card reader you are using.
# b) a group "scard" where all users allowed access to the
# card reader are listed
# c) a Linux kernel supporting hotplug and usbdevfs
# d) the hotplug package (http://linux-hotplug.sourceforge.net/)

# In the usermap file, the first field "usb module" should be named
# "gnupg-ccid" like this script.
