** Description changed:
Connecting my Canon Digital IXUS 30 to my notebook just triggers the
import dialog and i can click import to start f-spot-import. Then F-Spot
asks me to choose my camera and lists the following:
Canon Digital IXUS 30 (normal mode), usb:
Canon Digital IXUS 30 (normal mode), usb: 003,012
I tried both, F-Spot just gives an "Unknown Error".
As I was having problems with this camera on previous versions, too, i
know that the camera only supports PTP mode, which doesn't show up in
the list. I remember adding a line to my udev rules to fix this problem
in previous version, but in hardy there is no file like
/etc/udev/rules.d/*-libgphoto2.rules.
Creating /etc/udev/rules.d/45-libgphoto2.rules with the following
content doesnt help either:
SYSFS{idVendor}=="04a9", SYSFS{idProduct}=="30c0", MODE="0660",
GROUP="plugdev"
to be sure i didn't mess up the ids, heres the output of lsusb:
# lsusb | grep -i canon
Bus 003 Device 013: ID 04a9:30c0 Canon, Inc. Digital IXUS 30 (PTP mode) /
PowerShot SD200 (PTP mode)
Why is the rules file missing and how is PTP expected to work without
it?
+
+ Further information:
+
+ I just found the file
/usr/share/hal/fdi/preprobe/10osvendor/20-libgphoto2.fdi which contains
information on the access methods used by libgphoto, by default this file
contains two matching entries for the IXUS 30:
+ <match key="usb.vendor_id" int="1193">
+ <match key="usb.product_id" int="12480">
+ <merge key="info.category" type="string">camera</merge>
+ <append key="info.capabilities" type="strlist">camera</append>
+ <merge key="camera.access_method" type="string">proprietary</merge>
+ <merge key="camera.libgphoto2.name" type="string">Canon Digital IXUS 30
(normal mode)</merge>
+ <merge key="camera.libgphoto2.support" type="bool">true</merge>
+ </match>
+ </match>
+ <match key="usb.vendor_id" int="1193">
+ <match key="usb.product_id" int="12480">
+ <merge key="info.category" type="string">camera</merge>
+ <append key="info.capabilities" type="strlist">camera</append>
+ <merge key="camera.access_method" type="string">ptp</merge>
+ <merge key="camera.libgphoto2.name" type="string">Canon Digital IXUS 30
(PTP mode)</merge>
+ <merge key="camera.libgphoto2.support" type="bool">true</merge>
+ </match>
+ </match>
+
+ So obviously F-Spot only shows up the first one.
+ I installed gphoto2 to use its command line interface to do some more
debugging and got the following:
+
+ $ env LANG=C gphoto2 --list-cameras | grep "IXUS 30 "
+ "Canon Digital IXUS 30 (normal mode)" (EXPERIMENTAL)
+ "Canon Digital IXUS 30 (PTP mode)"
+ $ env LANG=C gphoto2 --auto-detect
+ Model Port
+ ----------------------------------------------------------
+ Canon Digital IXUS 30 (normal mode) usb:
+ Canon Digital IXUS 30 (normal mode) usb:004,012
+
+ So it uses the normal mode by default, which fails.
+ Forcing PTP with --camera "Canon Digital IXUS 30 (PTP mode)" works fine and i
can access the camera via CLI.
+
+ So we need to get rid of the normale mode access method, so that all
+ applications will use the working PTP mode to access the camera.
+
+ I tried to remove the corresponding lines in the 20-libgphoto2.fdi,
+ restarting HAL and replugging my camera, but that didn't have any
+ effects.
