Digital camera connection problem

errantowl · 2012-11-30 05:05:13

I am having trouble connecting a Canon DSLR in CrunchBang. When I plug the camera in to the computer with the USB cable, nothing happens--it does not detect it like it does with a USB flash drive. I check the File Manager and no "camera/drive" is displayed. I tried gphoto2 in the terminal and it can detect the camera but has an error trying to connect to it. I tried darktable and Rawstudio--darktable freezes when scanning for devices, but it can detect the camera in its open dialog when choosing to load images--however, then the same thing, it has error when trying to connect. And again, the same in the Rawstudio--it can detect the camera when using the open dialog, but cannot connect.

I am really loving CrunchBang Waldorf and its customized Openbox environment and workflow, and don't want to have to switch systems to get the camera to connect. Does anyone have any suggestions?

I am getting this error message in the open dialog:

Error initializing camera: -1: Unspecified error

I am getting this error message in the terminal using gphoto2:

*** Error ***
PTP I/O error

*** Error ***
An error occurred in the io-library ('Unspecified error'): No error description available
*** Error (-1: 'Unspecified error') ***

At one time you had to be root to mount cameras, so it might just be a permissions problem.
Try mounting it as root using sudo.

Thanks for the suggestion. I am still getting an error, though, even when using sudo gphoto2 in the terminal. I have upadted the original post to show this error.

I tried connecting my eos 40D the first time eith my system and it worked out of the box in nautilus. Sudo wasn't necessary.
Below is what my

/var/log/messages

told me:

Opening the content by using rawstudio directly wasn't possible, Rawtherapee and AfterShotPro didn't worked either. I think the reason for that is perhaps, because the device is not mounted in /media .

I'If you want, I can post other log's for comparing too.

Thanks for the information. I have figured out that the camera is not working connected to a USB 3.0 port, but it does work (somewhat) connected to a USB 2.0 port. It "sometimes" detects the camera in darktable and I am able to import RAW or JPG files. I am not sure why it is there sometimes and not there at other times. There still seems to be no recognition of the camera in the Thunar file manager, though.

hmmm, Thunar doesn't work for me too...
I normally use a card reader for transfering the files.

Yes, a card reader might be a good idea. The most intuitive connection method (at this time) for using the camera plugged into the computer seems to be using the USB 2.0 port with gphoto2 in the terminal or gphoto2 in the gtkam GUI and saving the image files from there to the local disk. Then, the images can opened from the local disk in the processing/editing software.

I am really liking Rawstudio--darktable has more features, but the layout and workflow and minimal default processing in Rawstudio are very nice. It is also nice how with Rawstudio the adjustments and settings are stored alongside the images in their own folder, making it easy to move folders of images around--or even move individual images if you move the three files that pertain to each image with it, one for the metadata, one for the settings, and one for the thumbnail.
