Problem: I would like to have my camera be mounted automatically when I plug it into its usb cable.
NB: Although it is plugged into the usb, it is seen as a scsi device.
I have a line in fstab:
/dev/sda1 /media/usbdisk auto pamconsole,exec,noauto,managed 0 0
I have made a dimage.rules file for udev:
BUS="scsi", SYSFS{model}="DiMAGE F100", KERNEL="sd?1", SYMLINK="camera"
I got some of this information by entering the command:
udevinfo -a -p 'udevinfo -q path -n /dev/sda1'
This is the output I get:
device '/sys/block/sda/sda1' has major:minor 8:1
looking at class device '/sys/block/sda/sda1':
SUBSYSTEM=="block"
SYSFS{dev}=="8:1"
SYSFS{size}=="493979"
SYSFS{start}=="101"
SYSFS{stat}=="

0 0"
follow the "device"-link to the physical device:

couldn't open device directory
Perhaps of note is the fact that the number on the line SYSFS{stat} is not the same every time
Also, the note at the end of the output for this command: "couldn't open device directory"
Is that normal? Why couldn't directory be opened? When I manually mount, it opens just fine.
When I plug in the camera:
- the modules are loaded automatically (verified with tail messages, etc)
- the aforementioned line appears in fstab
- /dev/sda1 is created
- a link /dev/camera --> /dev/sda1 is created
- /media/usbdisk is created
However, the camera is not mounted and I have to do so manually :-(
When I turn off the camera:
- /media/usbdisk disappears, but only after a very long time (in
a few instances it didn't disappear and on next boot, when I plugged in
the camera again, /media/usbdisk1 was created, in addition to the
pre-existing /media/usbdisk from the previous session)
- the line in fstab also disappears (I would have preferred to
have /media/camera, but usbdisk appears no matter what I write in
fstab, so instead of fighting it, I decided that it will have to do,
unless someone knows why...)
Does anyone know how to get this working? Help would be much appreciated.
