Hello,

Thank you for reporting in detail.

While I don't know about pcscd crash, I explain how to use card reader /
token with internal ccid driver of GnuPG.

You need a configuration file to allow USB access by user, when you use
internal ccid driver of GnuPG.

Please create a file /etc/udev/rules.d/yubikey-neo-otp-ccid.rules
with the content of:

---------------- /etc/udev/rules.d/yubikey-neo-otp-ccid.rules
ATTRS{idVendor}=="1050", ATTRS{idProduct}=="0111", MODE="664", GROUP="plugdev"
----------------

And please add yourself as a group member of "plugdev".

In my case, I have this line in /etc/group:

    plugdev:x:46:gniibe

If this works, the udev line should be included into scdaemon package in
future, so that each user doesn't need to configure.
