How to access a canon digital camera on FC9
Hi friends,
I want to transfer images from canon camera (IXY digital 70) to my notebook (Fedora Core 9). Everytime I plug in the camera, following messages appear: usb 1-1: new high speed USB using ehci_hcd and address 9 usb 1-1: configuration #1 chosen from 1 choice usb 1-1: New USB device found, idVendor=04a9, idProduct=311c usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 1-1: Product: Canon Digital Camera ------------------ I can't see any error messages above, but I also don't know, how to actually mount the camera so that I can access it. Is there any way to figure out the appropriate device (for e.g. /dev/sda etc) from the above information. Any pointers? Sanjay |
On my system (PCLOS) my Canon camera is auto-detected and I am given options including mounting in a new window and opening with Digikam. If I simply try to display in a Window, I see a folder named "USB ptp-class camera", but I cannot open the folder.
Digikam, however, will display the images and offer to download them (Just as if I had installed the card into a a reader. Note that the camera has to be switched to playback before any of this happens. I prefer using a separate card reader to get my images into the computer. |
Thanks Pixellany,
Inserting he SD card directly worked for me. Still I would be interested in knowing how can I make this work by directly attaching the camera. Is it possible for you to provide me the log messages (/var/log/messages) that appear when you insert your camera? Thanks Sanjay |
Code:
Aug 13 04:56:02 localhost kernel: usb 4-4.3: new high speed USB device using ehci_hcd and address 10 |
Thanks Pixellany,
Playback mode means the mode used to see pictures. Right :). Further, one more piece of information if you can provide. That is, what is the output of "mount" command on your system? This will just allow me to see which device is getting mounted and with what filesystem type. Sanjay |
"mount" does not appear to show anything relevant:

Thanks again.
Strange. Isn't it? |
If Canon supports Linux for cameras the same way they do for printers, then I'll stick with using a card reader.
More generally, I am pretty clueless about the various ways that Linux auto-detects things. On my list of things to do before I die....... |

May be you can read about how 'hot-plugging' works in linux and share you knowledge :)(I think we can classify it as hot-plugging). In general terms, whenever you hot-plug a devices, it sends a interrupt which is captured by linux-hotplug driver. This kernel driver then reads the configuration space of device (basically some registers on the device with predefined locations for various info) and locates the device id, manufacturer etc etc and pass this information to user space. The user space script reads this information and inserts appropriate device specific driver. |
I think that you'll find the card reader will transfer faster than the camera's usb cable.

photos from (some) canon cameras can be downloaded using gphoto2.
Program is available here. But first check if your camera is supported. |
