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.
