You need to make sure to use the interal CCID driver and not pcscd.
This requires proper setting of the permissions as explained int the
smart card how to and that you don't run pcscd!

To test this you should enter

debug 2048
log-file /somewhere/scdaemon.log

into scdaemon.conf and kill a running scdaemon process.  Instead of
the log file you may also use watchgnupg as explained in the manual.

There is no support for PIN pads when using pcscd.
