Connecting and Removing Smart Card Readers
To speed application startup, the last detected smart card reader information is cached. If the configuration of the attached smart card readers changes, the user must explicitly tell the system to query for changes in peripheral devices. This applies both to connecting and removing smart card readers.
Use the command ctconf -q or ctconf --query to perform a full device scan on all available serial ports. Alternatively, a system reboot or an HSM reset will initiate a full detection cycle on the next application startup.
