Hey guys,

My saga continues trying to get my Kodak DC6490 camera to get a USB 
storage device (i.e., /dev/sda1) associated with it. I'm using Debian 
Sarge/2.6.9-1-smp with udev.

I'm thinking that somewhere in either hotplug or udev land, the event is 
getting dropped (presumably a config problem).

I added the following lines to the top of the /sbin/hotplug script:
    logger -s -t CJC::hotplug `env`
    logger -s -t CJC::hotplug-cmdline "$@"

Low and behold, when I plug the camera in and hit its "sync" button, I 
get these lines appearing in /var/log/syslog:


> Nov 28 01:32:26 localhost kernel: usb 2-1.2: new full speed USB device using address 13
> Nov 28 01:32:26 localhost CJC::hotplug: DEVPATH=/devices/pci0000:00/0000:00:1d.1/usb2/2-1/2-1.2 PATH=/sbin:/bin:/usr/sbin:/usr/bin ACTION­d PWD=/ SHLVL=1 HOME=/ SEQNUM0 _=/usr/bin/env
> Nov 28 01:32:26 localhost CJC::hotplug: DEVPATH=/devices/pci0000:00/0000:00:1d.1/usb2/2-1/2-1.2/2-1.2:1.0 PATH=/sbin:/bin:/usr/sbin:/usr/bin ACTION­d PWD=/ SHLVL=1 HOME=/ DEVICE=/proc/bus/usb/002/013 INTERFACE=6/1/1 PRODUCT@a/575/100 TYPE=0/0/0 SEQNUM1 _=/usr/bin/env
> Nov 28 01:32:26 localhost CJC::hotplug-cmdline: usb
> Nov 28 01:32:26 localhost CJC::hotplug-cmdline: usb
> Nov 28 01:32:27 localhost usb.agent[8506]:      libgphoto2: loaded successfully

So I have good reason to believe that the hotplug script catches the event.

So then I added a file named /etc/udev/rules.d/10-local.rules, with the 
following content:
> KERNEL="*", PROGRAM="logger -s -t CJC::/etc/udev/rules.d/10-local.rules", NAME="foo%k"
> 
> SYSFS{manufacturer}="Eastman Kodak Company", SYSFS{serial}="KCTCT42820593", NAME="%k", PROGRAM="logger -s -t CJC::/etc/udev/rules.d/\
> 10-local.rules", SYMLINK="/dev/jenns-camera"
> 

The first rule was just an attempt to get udev to print SOMETHING, 
ANYTHING to syslog when I hit the camera's sync button. But adding these 
rules didn't cause any change in what I see from /var/log/syslog when I 
sync the camera.

Does anyone have any ideas about where this process (or my 
understanding) might be falling down?

Also, does anyone know why when I sync the camera, I see the addition of 
TWO distinct devices?:
DEVPATH=/devices/pci0000:00/0000:00:1d.1/usb2/2-1/2-1.2    and
DEVPATH=/devices/pci0000:00/0000:00:1d.1/usb2/2-1/2-1.2/2-1.2:1.0

Thanks,
Christian
