Summary: Incorrectly treating mass storage digital camera (lumix
tz3) - hald problem
Product: openSUSE 10.3
Version: Final
Platform: i586
OS/Version: openSUSE 10.3
Status: NEW
Severity: Major
Priority: P5 - None
Component: Hotplug

Hi
I had lots of trouble with this problem. I have Panasonic lumix dmc-tz3 digital
camera (this will surely apply to other similar cameras like TZ2, TZ1, LX2
..), I'm using KDE. The problem is when I plug the camera into USB,I cannot
access any filen in the camera.
I searched on Internet and I got interesting conclusion:
- it is mass storage camera (you can see my experiment at the end and also the
messages)
- it works correctly (in windows, it is indeed detected as mass storage without
any drivers needed. Also lots of people say it works well in other linuxes like
ubuntu, mandriva and probably in older opensuse)
So I looked at the kernel messages and I now know there is some problem with
HALD who is umounting sdb1 just after it's mounted (sdaX are my internal ATA
hard drives). Unfortunately I couldn't reproduce that message today. Instead
I'm joining several messages I got today from multiple USB cable plugs to
camera and one plug of my USB stick.
So in conclusion there is some weirg HALD configuration for this and it seems
it treats my camera both like usb mass storage AND as a camera (really dunno
hot it works)
Hope this gets fixed soon. Thanks.
Here I post some log messages:

So the sdb devices are now created and not destroyed.
Let's just mount the camera:
# mount /dev/sdb1 /mnt/a
# mount
..
/dev/sdb1 on /mnt/a type vfat (rw)
TADA!

Summary: Incorrectly treating mass storage digital camera (lumix
tz3) - hald problem
Product: openSUSE 10.3
Version: Final
Platform: i586
OS/Version: openSUSE 10.3
Status: NEW
Severity: Major
Priority: P5 - None
Component: Hotplug
AssignedTo: bnc-team-screening@xxxxxxxxxxxxxxxxxxxxxx

Hi
I had lots of trouble with this problem. I have Panasonic lumix dmc-tz3 digital
camera (this will surely apply to other similar cameras like TZ2, TZ1, LX2
..), I'm using KDE. The problem is when I plug the camera into USB,I cannot
access any filen in the camera.
I searched on Internet and I got interesting conclusion:
- it is mass storage camera (you can see my experiment at the end and also the
messages)
- it works correctly (in windows, it is indeed detected as mass storage without
any drivers needed. Also lots of people say it works well in other linuxes like
ubuntu, mandriva and probably in older opensuse)
So I looked at the kernel messages and I now know there is some problem with
HALD who is umounting sdb1 just after it's mounted (sdaX are my internal ATA
hard drives). Unfortunately I couldn't reproduce that message today. Instead
I'm joining several messages I got today from multiple USB cable plugs to
camera and one plug of my USB stick.
So in conclusion there is some weirg HALD configuration for this and it seems
it treats my camera both like usb mass storage AND as a camera (really dunno
hot it works)
Hope this gets fixed soon. Thanks.
Here I post some log messages:

So the sdb devices are now created and not destroyed.
Let's just mount the camera:
# mount /dev/sdb1 /mnt/a
# mount
..
/dev/sdb1 on /mnt/a type vfat (rw)
TADA!
