This version of libchipcard should do event-based hardware device detection by default. If it doesn't, probably your configuration hasn't been updated to do so, when upgrading from libchipcard-data 4.1.3-2ubuntu1 to libchipcard-data 4.2.8-1ubuntu1.
Can you please submit the contents of the file /etc/chipcard/server/chipcardd.conf on your system?
Especially the value of the variable hardwareScanInterval in section DeviceManager is of interest. You can safely set it to zero with the libchipcard 4.2.8.
Are you still interested in fixing the bug?
