$in · 11-29-2005, 11:34 AM

need some help here.
i can't get to work my canon powershot a95. i compiled from source libgphoto2, ghoto2 and gtkam. when i try gphoto2 --auto-detect i get nothing. the same goes for trying with gtkam. some time ago i borrowed some hp digicam and it worked alright.
tried google and

but nothing helped
i'm using slack 10.2 and 2.4.31 kernel.

what's the output of dmesg | tail.

and also, here's what worked for me but i give no guarantees if this would work for you or not. but try it anyways.

1. using root create a group called "camera" (without the quotes...)

2. Still as root - add your user to that group (the non-root user)

3. Log out and then back in (to reset your groups).

4. Either rename /etc/hotplug/usb.usermap.new to usb.usermap or copy its contents across (cat usb.usermap.new >> usb.usermap).

Now, when you plug in the camera it should appear under /proc/bus/usb/devices and you should be able to access it through gphoto2/digikam/whatever other front-end you choose.

Code:

mount -t vfat /dev/sda1 /mnt/camera

always works for me. That's assuming you've created the directory /mnt/camera and only have one usb device plugged in.

$in · 11-29-2005, 04:45 PM

dmesg | tail

Code:

Furlinastis, i'll try that with the groups and get back with the results

thank you for the quick replies!

edit:
tried that and nothing happend, still the same, the camera can't be detected

Furlinastis · 11-29-2005, 06:08 PM

"mount: /dev/sda1 is not a valid block device"

that's telling you there is no device at /dev/sda1 and you might try a different file.

try cat /proc/bus/usb/devices and look to see if the camera is being detected...but after that, I'm lost

Namaseit · 11-29-2005, 10:50 PM

cat /proc/partitions

if its going to be recognized as a mass storage device you'll see it in that listing.

How d'ya like that! I've been plagiarised...

Here's a link to my site which fully explains all the above.

http://members.optusnet.com.au/rkelsen/camera.html

Note: Step 4 of that process won't work unless you install the packages from the site linked to above. The packages are a bit old now (August 2004), but work fine for me on Slackware 10.2 with a Canon Powershot A85.

P.S. No hard feelings brokenflea. Just remember to credit your sources next time...

I also pwn a Canon95a camera and some time ago I wanted to get it functional in slackware.
I wanted to mount camera as any flash drive (i guess that was my mistake). Here's what ive had done:
1. plug the camera into usb, turn the device on
2. do a lsusb, find the bus number the camera is on
3. do a usbmosules --device /proc/bus/usb/[bus/slot id], this lists required modules for device to function (well i think so)
4. do a modprobe on the found modules
5. do a mount /dev/sdaX /mnt/camera -t auto to mount the device

Well sadly it didnt work for me (maby it works for someone else), sinc then i have given up a bit on accesing my camera from linux. Still I recently downloaded libgphoto and stuff packages, so I will be testing same crap soon.

:^)

In my experience, Canon cameras support only PTP. This means that you cannot access the camera like a storage device. You must use libgphoto. There are some Slackware packages of the required software at the site in my previous post.

gbonvehi · 11-30-2005, 04:27 AM

There are packages for a newer version (2.1.6) of gphoto/libgphoto in linuxpackages.net. Those worked fine for a guy with a Kodak camera I talked to in ##slackware@freenode.net

$in · 11-30-2005, 04:46 AM

rkelsen, thank you very very much! you saved the day

this was the crucial thing:

2. Be sure to have the camera in 'playback' mode, or it won't be detected.

LoL

i was like "dough!!!" :c)

and thank you everyone else for the replies!
