Bug#394684: libgphoto-2: privilege problem with PTP mode camera
Hi Marco
I did some investigations into the libphoto2 udev rules issue, maybe
this helps you finding a solution. (I am using udev 0.100-2.2,
libgphoto2-2 2.2.1-10, kernel 2.6.18-2-686 2.6.18-4)
The camera I use here is an older one (HP Photosmart R507) which used
to work with sarge and hotplug. Which means a lot of cameras where no
explicit vendorid .. is provided, will not be supported only because
the devices does not get the right groups. :(

If I comment out the above lines, the following devices get the
plugdev group
/dev/usbdev2.7_ep81
/dev/usbdev2.7_ep01
/dev/usbdev2.7_ep82
but not /dev/bus/usb/002/007 which is used to get access to the
photos.

With the rules provided in libgphoto2-2 no device gets the plugdev
group.

Sorry to bother you again, but there is still one problem; consider
this rules file:
ACTION!="add", GOTO="libgphoto2_rules_end"
SUBSYSTEM=="usb_device", GOTO="libgphoto2_rules_real"
SUBSYSTEM=="usb", GOTO="libgphoto2_rules_real"
BUS!="usb", GOTO="libgphoto2_rules_end"
LABEL="libgphoto2_rules_real"
SYSFS{idVendor}=="04a9", SYSFS{idProduct}=="30fd", \
MODE="0660", GROUP="plugdev"
SYSFS{bInterfaceClass}=="06", SYSFS{bInterfaceSubClass}=="01", \
SYSFS{bInterfaceProtocol}=="01", \
MODE="0660", GROUP="plugdev"
LABEL="libgphoto2_rules_end"
It will match my camera on its USB ID and it will work fine.
What I would like to achieve would be that if a specific USB ID can't
be matched, at least there is a generic rule matching 'PTP camera' and
it works without adding a new rule.
Unfortunately the rule as it is written now doesn't work, could you
enlighten me on this, how can I match against bInterface* when a
camera is plugged ?
Thanks,
Frederic

Bug#394684: libgphoto-2: privilege problem with PTP mode camera
Hi
Sorry for the delayed answer.
> Could you try 2.2.1-7; Fuji F30 was added in this version.
Yes with this version it works.
But it seems that the hotplug rules of libgphoto2 are better than the
udev rules, because sarge can handle this camera. So any PTP camera
released after etch will not work with etch but with sarge?
To my understanding the rule
SYSFS{bInterfaceClass}=="06", SYSFS{bInterfaceSubClass}=="01",\
SYSFS{bInterfaceProtocol}=="01", MODE="0660", GROUP="camera"
should match. When I connect the camera
/sys/bus/usb/devices/1-8/1-8:1.0
contains bInterfaceClass, bInterfaceSubClass, bInterfaceProtocol with
the correct entries.
So maybe this is an udev bug?
I experimented a bit and at least the rule
SYSFS{product}=="USB PTP Camera", MODE="0660", GROUP="camera"
matches as well and gives the right permissions. I am not shure if
this rule is as global as the not working (bInterfaceClass ...) one.
Maybe this problem can be forwarded to upstream as well?
Thanks

Hi
> Which version of libgphoto2 are you using ?
dpkg --status libgphoto2-2
Version: 2.2.1-4
I think the udev config stuff is as the package provided it.

I think it should be ls -l /etc/udev/libgphoto2.rules
-rw-r--r-- 1 root root 45480 2006-10-19 20:55 /etc/udev/libgphoto2.rules
I am not very much into udev rules. lsusb provides the following infos
...
bInterfaceClass 6 Imaging
bInterfaceSubClass 1 Still Image Capture
bInterfaceProtocol 1 Picture Transfer Protocol (PIMA 15470)
...
and this rule from /etc/udev/libgphoto2.rules should match it
SYSFS{bInterfaceClass}=="06", SYSFS{bInterfaceSubClass}=="01",
SYSFS{bInterfaceProtocol}=="01", MODE="0660", GROUP="camera"
But find "/dev -group camera" does not find any device file.

I think the device is too new. At least gphoto2 --list-cameras does
not list it. But it works perfectly on a sarge (using hotplug) system
as normal user.

I also tried with gtkam. Works as root, does not as user in group
camera.
By the way is straced digikam. The last accessed device when failing
access the camera is /dev/bus/usb/001/005
12872 open("/dev/bus/usb/001/005", O_RDWR) = -1 EACCES (Permission denied)

Package: libgphoto-2 Severity: important *** Please type your report below this line *** My camera Fuji Finepix F30 works in USB PTP mode.
