It may be a bug in the libifd-cyberjack6 driver. Can you run pcscd inside gdb and gerenate a backtrace? Do: $ gdb /usr/sbin/pcscd $ set args -dfa $ run generate the crash $ backtrace
And send me the complete output of gdb -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pcsc-lite in Ubuntu. https://bugs.launchpad.net/bugs/1323795 Title: pcscd crashes when removing usb chipcard reader Status in “pcsc-lite” package in Ubuntu: New Bug description: pcscd (1.8.10-1ubuntu1) crashed reproducibly in Ubuntu 14.04LTS when I remove my Reiner SCT chipcard reader. The reader uses the libifd-cyberjack6 driver. I tried with the driver version from the Ubuntu repositories first, when that failed I also tried with the ones provided from the manufacturer's homepage, but pcscd crashes in both cases. I ran pcscd in debug mode attached the chipcard reader, inserted and removed the chipcard a couple of times and got this output: /usr/share/doc/libusb-1.0-0 $ sudo pcscd -d -f 00000000 pcscdaemon.c:240:main() pcscd set to foreground with debug send to stdout 00000158 configfile.l:254:DBGetReaderListDir() Parsing conf directory: /etc/reader.conf.d 00000033 configfile.l:307:DBGetReaderList() Parsing conf file: /etc/reader.conf.d/libccidtwin 00000046 configfile.l:266:DBGetReaderListDir() Skipping non regular file: . 00000012 configfile.l:266:DBGetReaderListDir() Skipping non regular file: .. 00000013 pcscdaemon.c:545:main() pcsc-lite 1.8.10 daemon ready.
