I removed the PCMCIA card reader, yes.

I discovered that performing the tests described below :-(

SUBSYSTEMS=="pcmcia", DRIVERS=="serial_cs", ACTION=="add", \
ATTRS{prod_id1}=="Gemplus", ATTRS{prod_id2}=="SerialPort", \
ATTRS{prod_id3}=="GemPC Card", RUN+="/usr/sbin/pcscd --hotplug"
This rule only work when inserting the PCMCIA reader, even if I change
ACTION=="remove" or I completely delete ACTION (the rule should be then
always effective).
BTW, mimicking the rules for USB readers, the rule above can simply be:
SUBSYSTEMS=="pcmcia", ATTRS{manf_id}=="0x0157", \
ATTRS{card_id}=="0x0100", RUN+="/usr/sbin/pcscd --hotplug"
Since this rule still detects insertion only, I guess the PCMCIA stack
is not completely udev compatible.
I finally found how to detect both events (insertion/removal):
MODALIAS=="pcmcia:m0157c0100f02fn00pfn00pa0981590FpbE9010D26pcDDC63BD8pd00000000",
\
RUN+="/usr/sbin/pcscd --hotplug"

I think this bug is the sum of three different bugs:
1) pcscd init scripts can set the debug level (option $DAEMON_ARGS), but
there's no easy way to do it (e.g. in /etc/default/pcscd).
2) libccid ships udev rules that depend on pcscd, which is only
recommended by libccid. I'd suggest to ship these rules in pcscd,
instead, since the latter depends on libccid anyway.
3) an udev rules to detect PCMCIA card readers insertion/removal would
be nice.
If no one replies in one week, going to clone, retitle and reassign the
bugs accordingly to what explained above.
Thx, bye,
