Package: libgphoto2-2
Version: 2.1.6-5.3
Severity: grave
Justification: renders package unusable
I am using udev unstable, version 0.076-4.
libgphoto2 generates a set of rules for use with udev, namely
/etc/udev/libgphoto2.rules. These in turn call the executable
/etc/hotplug/usb/libgphoto2, which attempts to set the group of the device
that's created by udev to $GROUP, in this case "camera."
This does not work in the current version of udev. First, the script relies on
the undocumented $DEVICE variable; second, the script is called multiple times.
Finally, and most importantly, the $DEVICE variable resolves to paths such as
"proc/bus/usb/002/017", but what's really needed is "/dev/bus/usb/002/017".
To fix this problem, the libgphoto2.rules should read as follows
# Canon S110
SUBSYSTEM=="usb_device", SYSFS{idVendor}=="04a9", SYSFS{idProduct}=="3051",
GROUP="camera"
Translation: When the usb_device subsystem creates the /dev entry
(/dev/bus/usb/002/017, as can be seen with by running "udevmonitor --env" and
watching plug/unplug events), and when the vendor and product IDs are correct,
then set the GROUP of the created /dev entry to "camera."
Note that this is done entirely internal to udev, with no outside script. It's
possible to deprecate libgphoto2.
If I've made an error, my apologies. If you need further information about my
system configuration, or log files, please contact me.
