Once you download and install that driver ( ProxKey_Redhat.rpm ), it does a few things — installs a separate pcsc daemon named pcscd_wd , installs the driver CCID bundles and certain supporting binaries/libraries. Note that this package installs the TRUSTKEY driver (/ usr/lib/WatchData/TRUSTKEY/lib/libwdpkcs_TRUSTKEY.so ), not ProxKey driver ( /usr/lib/WatchData/ProxKey/lib/libwdpkcs_SignatureP11.so ) and it seems the ProxKey token only works with TRUSTKEY driver!
