Gphoto2 Fails communicating with Canon SD200 (PTP Mode). This bug is present in the following packages: =media-gfx/gphoto2-2.4.1 (aalib exif ncurses nls readline) =media-libs/libgphoto2-2.4.1 (exif hal nls -doc) =media-libs/libgphoto2-2.4.1-r1 (exif hal nls -doc) Reproducible: Always Steps to Reproduce: 1. Upgrade to the above listed (marked stable) versions 2. gphoto2 -L will fail communicating with camera 3. (And f-spot depends on gphoto2, as such, will fail communicating also.) Actual Results: Here's gphoto2's output: Error -114: LibGPhoto2.GPhotoException: Unknown Error Here's f-spot's output for kicks: f-spot can not import: Could not claim the USB device Expected Results: gphoto2 should recognize and list images available for download on the camera For temporarily working around this issue, with effort focused on keeping f-spot working, users can depend on the following packages to still work. =media-gfx/gphoto2-2.2.0 =media-libs/libgphoto2-2.2.1-r1 I have masked the stable versions, or versions I verified the problem existed in: /etc/portage/package.mask =media-gfx/gphoto2-2.4.1 =media-libs/libgphoto2-2.4.1 =media-libs/libgphoto2-2.4.1-r1 Gphoto2 developers request --debug log, unfortunately, I might still have a logged output on my laptop. If I get to it before somebody else posts theirs, I push it to this page. This is more then likely an upstream bug. However, haven't ruled out patches applied by this ebuild, etc.
Your emerge --info, please.
Just doing some research and found another on the Gphoto2-users mailing list post this topic: "[Gphoto-user] Canon IXUS 30/Powershot SD200 doesn't work anymore" However, posting trails off and I don't think the issue was ever really resolved. Gphoto2 seems to be trying to use the "normal mode" driver instead of the working "ptp mode" driver. Even forcing gphoto to try PTP mode, would still get the same error.
Created attachment 155195 [details] Gphoto2 debug output (Possibly compiled with cameras_canon USE Flag?) Posting yesterdays debug log file. (Log file might have been obtained from using the cameras_canon USE flag.)
Created attachment 155197 [details] Debug file from Gphoto2 =media-gfx/gphoto2-2.4.1 (aalib exif ncurses nls readline) =media-libs/libgphoto2-2.4.1 (exif hal kernel_linux nls) Yup, definitely trying to use the Normal Mode driver instead of the PTP driver. (Think they committed a patch causing libgphoto2 to give priority to this driver over PTP driver? It seems not even trying to use the PTP driver.)
Created attachment 155201 [details] Explicitly specifying PTP Mode results in hang It took me awhile, but I've figured out how to force ptp mode with the following: # env LANG=C gphoto2 --debug --debug-logfile=my-logfile.txt --camera "Canon PowerShot SD200" --port "ptpip:" -L However, all I get is a hang while communicating and something about a bad parameter (after I think the camera times out).
Please do post your emerge --info, and then reopen this bug.
Taking this issue up with the Gphoto2 mailing list instead.

I've verified this. My camera model again: Canon PC1102 - Detected in gtkam as a Canon Digital IXUS 30 (PTP Mode) Compiling libgphoto2 (media-libs/libgphoto2-2.4.3) with USE flag "-cameras_canon" causes libgphoto2 not to be able to detect my camera. If I'm correct, this is likely an upstream bug with it's configure, Makefiles or code headers.
# eix -s libgphoto Installed versions: 2.4.3!t(01:33:12 07/14/09)(exif hal kernel_linux nls ... all other USE flags for libgphoto disabled, and it works. Enable cameras_canon USE flag and the camera fails detection.

Enable > cameras_canon USE flag and the camera fails detection. That's is because cameras_canon is for old canon cameras that uses a specific protocol and/or serial cable. You need ptp2 which is the generic PTP support. Not setting any USE flag is equivalent to enabling all of them. That's how IUSE_EXPAND works.
So maybe using a use flag a little more descriptive would be more appropriate? ie. User has a canon camera and automatically assumes to enable "cameras_canon" within make.conf? Something like "cameras_canon_old", "cameras_canon_nonptp", or "cameras_nonptp_canon"?
well you set the summary so it seems you failed to understand the correlation between PTP and cameras_ptp2. Better descriptions are always welcomed but changing the useflag is no go.
Comments #3, #4, #5, I started understanding somewhat what was going on. Then I trailed-off, guessing because I found the solution and failed to follow-up. The topic was set during a time I completely didn't understand what was going on. Depending on a user to understand their Canon camera uses PTP mode to communicate vs. a USE flag called "cameras_canon" seems like a recipe for disaster, as specifying this use flag will cause gtkam & f-spot to be non-communicative with this canon (as well as other cameras). I see the calamity that is caused if cameras_ptp is only specified, preventing all other drivers from being compiled. Might I suggest at least a message to stdout during emerge: "PTP mode (cameras_ptp) is a suitable communication protocol used by most cameras even though their specific model is listed within the cameras_* USE flags. The default, specifying no cameras_* USE flags will build all camera communication protocols." In other words when programing a program with switches and arguments, they should be self explanatory as to what they do instead of cause confusion. ;-)
closing invalid since the original bug was due to a misunderstanding.
