Variables invloved with working camera/usb storage device connection

I had my camera/usb storage device working perfectly. Then this morning I was trying to mount it and it wouldīt mount... gave me the old īsda1 (which I know it was connected to) not a valid block deviceī.

After a while of playing around I went to suse 9, which I have because it makes me feel like I am using windows... but I am not (not dissing Suse) It was automatically mounted and worked perfectly (on SDA1)

I just came back to Slack, which is what I usually use. Trying everything I could think of but no luck. Opened up about 20 threads in this forum ready to get every bit of info that could be needed for you guys to figure out what was wrong.

One last go and it worked????? What I wanīt to know is what things/processes or variables can make it stop working?? After playing around I found that if I donīt have any photos in the camera it gives me the same error (But I had photos in there when I was trying to start with.

gphoto2 can't detect digicam

I'm using Slack 9.1, kernel 2.4.22. I couldn't get my pictures using gtkam, gphoto2 didn't auto detect my digicam. The camera is a CanonS400

Checking with /proc/bus/usb/devices, this is the output:
-$ cat /proc/bus/usb/devices
T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=12 MxCh= 0
D: Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=32 #Cfgs= 1
P: Vendor=04a9 ProdID=3075 Rev= 0.01
S: Manufacturer=Canon Inc.
S: Product=Canon Digital Camera
C:* #Ifs= 1 Cfg#= 1 Atr=c0 MxPwr=100mA
I: If#= 0 Alt= 0 #EPs= 3 Cls=06(still) Sub=01 Prot=01 Driver=(none)
E: Ad=81(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=02(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=83(I) Atr=03(Int.) MxPS= 8 Ivl=96ms

Is it right that the camera was detected? However, when i

-$ gphoto2 --auto-detect
Model Port
(nothing is detected)

and when i tried to checked cameras that gphoto2 supports

-$ gphoto2 --list-cameras
Number of supported cameras: 0
Supported cameras:

Is that the problem of gphoto2? Can anyone please show me how I can dl my pictures in the camera using gtkam or advise any other way to do the same thing?

Thanks heaps for your help.

Hey parfumi as you can se I am no expert but do you know if you camera can be used as a mass storage device?? If you can you can use it like a USB hdd. So you plug it in and mount it.

Assuming you wanted to mount it to /mnt/camera somthing like:
mount -t vfat /dev/sda1 /mnt/camera

this is assuming that it is sda1 (I find depending on which usb port I use it changes from sda1 to sda2.

This is only if you camera can be treated as a mass storage device.
