Strange udev issue with PTP camera

Spent a fustrating afternoon getting Arch to recognize my wife's new Canon S5 IS in PTP mode. Worked as root but not as user, could not track down the permissions problem; tried adding to camera group, creating custom udev rules, etc nothing worked.

Solution found:

Add "/etc/start_udev" to the end of /etc/rc.local (or execute command as root)

Camera now appears on plugging it in, starts digikam.

Udev does appear to be up, says it starts during bootup scroll, but without the extra(?) start neither gphoto2 nor digikam can see the camera as a non-root user. Perhaps a udev problem?

Don't see udev listed under the DAEMONS in /etc/rc.conf, but still says it starts on boot (hardcoded?)

Filed to the forum for the next poor soul who runs into this.

Re: Strange udev issue with PTP camera

I had the same problem than you and I found the same solution but I isolate the only interesant line in the start udev script :

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

I posted a message in the forum to know why but I had no answer
