Find out where your library for libpcsclite is, then run lsof on it like below:
lsof /usr/lib64/libpcsclite.so.1.0.0
lsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/1000/gvfs
Output information may be incomplete.
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
libvirtd 3461 root mem REG 253,2 47896 1081788
/usr/lib64/libpcsclite.so.1.0.0
pcscd 3462 root mem REG 253,2 47896 1081788
/usr/lib64/libpcsclite.so.1.0.0
upowerd 3606 root mem REG 253,2 47896 1081788
/usr/lib64/libpcsclite.so.1.0.0
You will probably get output similar to this. Then you can kill the pids, of
the processes that are blocking the card.
However, as I said, add systemctl restart pcscd a s a sudo option, which should
be much easier and not interfere with the other processes.
I hope this helps.
Regards,
Tristan
