Package: libtowitoko2 Version: 2.0.7-9 Severity: grave /etc/reader.conf.d/libtowitoko2 should not contain a DEVICENAME line as this driver does not support opening readers by device name, but the presence of the line in the config file triggers a bug in pcscd that always causes /dev/ttyS0 to be opened when a DEVICENAME line is present, no matter what else is configured.
Instead, it should be documented that "normal" serial devices start at CHANNELID 1 for /dev/ttyS0 and USB devices start at 0x200000 for /dev/ttyUSB0, and possibly the automatically generated /etc/reader.conf.d/libtowitoko2 should be removed completely (or made into a conffile), so as to not break a working manual configuration on each update/reinstall, given that the debconf options don't support every possible setup.
