That is a different problem than that with the Omnikey reader.  In your
case the permissions of the USB device don't allow you access.  pcscd
however runs as root and thus has no permission problems.  Having a
daemon running as root is not a good idea however.

If you have an very old SCM-335 you should even use the internal CCID
driver, because it has a workaround for the buggy USB stack in those old
readers.



Salam-Shalom,
