By design. The correct rule would be:
BUS==usb, SYSFS{idVendor}==046d, SYSFS{idProduct}==c025, \
RUN+=/usr/bin/lmctl -8 --sms
I doubt that switching from PROGRAM= to RUN+= will make a difference, as it
certainly didn't resolve the issue with kdebase. Perhaps you're not running
OK, as it turns out I was half wrong: /proc/bus/ is not syncronous, so
scripts still need to wait (they may use the wait_for_file function from
/lib/hotplug/hotplug.functions). OTOH, RUN is still the correct keyword
to use, because PROGRAM has different semantics (and you must always use
+= unless you know better).
This looks like the same issue of #334068, which I am reassigning for
libsane (I'm sorry for not getting it right the first time).
a modular kernel? I did notice that a homebrew everything-built-in kernel
did not suffer from this problem. I just took it for granted that the
udev/hotplug maintainer would be testing against a stock Debian kernel, or
at least something similarly modularized.
I need newer kernels before a debian package is available, and anyway I
will not use debian kernels again as long as they will break drivers
by removing uploadable firmwares.
worked fine when hotplugged later. The wait loop fixed it. A rule like:
SYSFS{idProduct}==0039, SYSFS{idVendor}==045e, MODE=660,
GROUP=plugdev
...changes the permissions of /dev/input/ nodes instead of usbfs entries,
which isn't very helpful in this case.
Because the rule matches on many events, among them BUS==usb.
The correct rule to change the /dev/bus/usb/ device permissions would
be:
SUBSYSTEM==usb_device, SYSFS{idProduct}==0039, SYSFS{idVendor}==045e, \
GROUP=plugdev
(660 is the default.)

What is the problem ? Coldplugging not running the old hotplug scripts ? I don't want to use a RUN rule in the rules file to take care of /proc/bus/usb. I want RUN rules to be available to the user to run a custom script. Colplugging should work with the old hotplug scripts, just as hotplugging does. And yet again, this whole hotplug/udev stuff is a complete obscure mess that nobody understands. Grmpf.

No, that there is a race between RUN rules and the time /proc/bus/usb/ files are created, so scripts tend to fail at boot time. I don't want to use a RUN rule in the rules file to take care of /proc/bus/usb. If you want to support /proc/bus/usb/ until /dev/bus/usb/ will become available, you need to. I want RUN rules to be available to the user to run a custom script. They are, as long as both you and users use RUN+= instead of RUN=. Colplugging should work with the old hotplug scripts, just as hotplugging does. Actually udev better supports coldplugging than hotplug, which does not run the hotplug.d/ scripts. -- ciao, Marco signature.asc Description: Digital signature
