The OpenSC smart card middleware can auto-detect smart card drivers; however by
forcing the smart card driver in use by your organization, opensc will no longer
autodetect or use other drivers unless specified. This helps to prevent
users from using unauthorized smart cards. The default smart card driver for this
profile is /etc/opensc.conf.
Look for a line similar to:
# force_card_driver = customcos;
and change it to:
force_card_driver = ;
