Package: udev
Version: 0.140-2
Hi udev maintainers,
when investigating the reasons for bug #524665 I discovered a
discrepancy between the udev man page and what apparently happens on
Joachim's system. The udev man page says in section "Rules files":
"The udev rules are read from the files located in the
default rules directory /lib/udev/rules.d/, the custom rules
directory /etc/udev/rules.d/ and the temporary rules directory
/dev/.udev/rules.d/. All rule files are sorted and processed in
lexical order, regardless in which of these directories they live."
In opposite to this Joachim experienced something different: The rules
in /lib/udev/rules.d/91-permissions.rules get applied after the rules
in /etc/udev/rules.d/z60_libchipcard-tools.rules. So the rules from
z60_libchipcard-tools.rules get overwritten by those from
91-permessions.rules even though "91-..." comes before "z60_..." in
lexical order.
Is this a bug in udev or did Joachim observe some weird special cases
(i.e. caused by a race condition)?
I definitely need your help. What do you suggest in order to fix the
bug?
Regards
Micha

Hi Micha,
for a while (probably since some udev upgrade), the file
/dev/bus/usb/003/006 (numbers vary, of course) do not have the proper
chipcard group setting any more.
I have attached a udev log with priority=info that shows what happens
when pluggin in my card reader. The settings from
/etc/udev/rules.d/z60_libchipcard-tools.rules do get applied, but are
later overridden by a line in /lib/udev/rules.d/91-permissions.rules:
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", \
MODE="0664"
Which, as it seems, also resets the group.
I assume that you need to change your udev rule number, or move it to
/lib or something. I guess you should consult the udev maintainers for
that.
Greetings,
Joachim
