Problem with the file /proc/sys/kernel/hotplug which is incorrect

Hello,

Since few days, I can't import photos from my camera with my user (that work in root), I open a thread in this forum (http://bbs.archlinux.org/viewtopic.php?pid=348659).

After investigations, the problem come from the content of the file /proc/sys/kernel/hotplug which is just :

-e

When I run the start_udev script, the content of /proc/sys/kernel/hotplug change and importing photos with my user work again.
I isolate the only important line for my problem :

echo -e '\000\000\000\000' > /proc/sys/kernel/hotplug

When I run this line after a boot, the import file from camera work.

I think that the content of the file is bas setted while the udev starting or replaced by another event which occurs later !

I use the x86 version up-to-date with kdemod.

Someone have an idea of why the content of /proc/sys/kernel/hotplug (it must contain an executable for kernel call on hotplugging) is bad ?
