pcscd CPU usage

[David L]

I've noticed several times that pcscd sucks a lot of CPU.
My uptime is 866 minutes and top is reporting that pcscd has
used 843 minutes of CPU and is currently using 99%:

 1856 root      20   0 44628 1608  764 S   99  0.2 843:20.24 pcscd

Is there anything I can try to provide some useful debugging
info?
