It is a PolicyKit issue.
Have a look at https://github.com/LudovicRousseau/PCSC/blob/master/doc/README.polkit

I don't know why the function failed.
Try to rebuild pcsc-lite with this patch to get more information.

Client protocol is 4:3
Server protocol is 4:4

You are using a pcscd with a libpcsclite.so.1 from 2 different versions of pcsc-lite. This can't work.
I guess you have installed pcsc-lite manually from a different version than the one from pcsc-lite SUSE package.

[emasean]

When we build ourselves the libpcsclite from the source it worked fine, but when we take the binary from the SUSE repo (same version) it fails, we will check with SUSE.
