hi all i just installed lmde wow its fast but my cannon power shot a495 camera is not working on usb & neither are my web cams
any ideas they worked fine on linux mint & ubuntu somethings missing but i cant seem to figure out what
thanks for any help

How are you trying to use the a495? When you attach it does nothing happen or does a pop up window appear with an option to open as a folder or F-Spot or another application? Is it that the application shuts down instead of accessing the camera? Or, is there absolutely no indication that you connected the camera?

With the camera attached and turned on, open a terminal and enter (that's a lowercase L) Please paste the output here, this should indicate if the camera is detected.

Is there a place in the camera's settings to determine how a USB connection is treated?

I have an Olympus Fe-4030 and I must choose from <Auto> <Storage> <MTP> and <Print>. When I connect my camera to the laptop with it set to Storage the dialog I mentioned above opens. if I select folder I can easily drag and drop files. I could then open F-Spot but it was a little fussy. If I connect the camera with it set to <Auto>, it has me choose from the other options from the camera display. When the camera USB is set to MTP and I connect the camera, there is no visible indication that the contact was successful. But, F-Spot will easily import photos from the camera. As an aside, lsusb returns different vendor IDs depending on which USB connection setting I have the camera set to. When it is set to MTP, the terminal output gives a model number of C-350Z, a model that came out 7 years ago. Mine came out in February this year, I believe.

OK, your camera seems to be newer than mine. so check it's set-up options.

As for the webcams, check them with lsusb also. I suggest only having one of these items connected at a time until you get this worked out. If any of them are detected with lsusb, install cheese and see if it can connect with the web cam(s) individually.

thanks for getting back
heres the terminal readout

the cam loads fine in mint & ubuntu ive checked the package manager but cant fugure out whats missing
p.s nothing happens when i put the camera in & even fstop says cannot claim the usb device wile connecting to the camera
thanks for any help

I did find this reference to MTP transfer

NTERFACE

Computer
Hi-Speed USB (MTP, PTP) dedicated connector (Mini-B compatible)

HERE

There is a link to the camera's manual on THIS page. Page 35 of the manual says you can transfer files to a computer w/o using their software, but it will take longer and may cause trouble w/ some images.

You could always speed things up by taking the memory card out of the camera and place it in a reader. Until you can find a tutorial on the web. Because of the comment from the Canon page, we will probably find it has something to do with using the mtp-tools package from the repositories.

i tried the mtp-tools but still no cam
i appreciate all your help this is the only problem i haven't solved
ill keep working on it it works in mint & ubuntu something has to be missing
thanks again

just install gtkam, that will recognize your canon camera.
this camera doesnot support usb mass storage
if you have more questions feel free to ask them, if necessary i'll make screenshots

thanks for the info but no cam
the a 495 is not listed tried all of the cannons with no results
any ideas you have are more than welcome

I made a small instruction with screenshots.

If its still not clear let me know

still no go
it works fine in mint 10 rc

weird

this week i'll make a lmde install and see how / if it works here

did you press the play / view button? it's the button just below the zoom button

installed LMDE and gtkam
and it does not work
and that is really strange, in Debian squeeze it just works
gtkam in LMDE and Debian squeeze have the same version number

error message in LMDE is " cannot initialize camera "

i suggest that you make a bugreport on launchpad, and in the meantime use a cardreader

bollie thanks for trying

Tadaaaaaaaaaa

it works

you must install mtp-tools
or just use synaptic / packet manager


strange thing is, on Debian squeeze i don't have to install mtp-tools, i'll adjust my little manual

tryed all that still no go
strange
