Hey guys,

My saga continues trying to get my Kodak DC6490 camera to get a USB=20
storage device (i.e., /dev/sda1) associated with it. I'm using Debian=20
Sarge/2.6.9-1-smp with udev.

I'm thinking that somewhere in either hotplug or udev land, the event is=20
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=20
get these lines appearing in /var/log/syslog:


> Nov 28 01:32:26 localhost kernel: usb 2-1.2: new full speed USB device us=
ing address 13
> Nov 28 01:32:26 localhost CJC::hotplug: DEVPATH=3D/devices/pci0000:00/000=

> Nov 28 01:32:27 localhost usb.agent[8506]:      libgphoto2: loaded succes=
sfully

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=20
following content:
> KERNEL=3D"*", PROGRAM=3D"logger -s -t CJC::/etc/udev/rules.d/10-local.rul=
es", NAME=3D"foo%k"
>=20
> SYSFS{manufacturer}=3D"Eastman Kodak Company", SYSFS{serial}=3D"KCTCT4282=
0593", NAME=3D"%k", PROGRAM=3D"logger -s -t CJC::/etc/udev/rules.d/\
> 10-local.rules", SYMLINK=3D"/dev/jenns-camera"
>=20

The first rule was just an attempt to get udev to print SOMETHING,=20
ANYTHING to syslog when I hit the camera's sync button. But adding these=20
rules didn't cause any change in what I see from /var/log/syslog when I=20
sync the camera.

Does anyone have any ideas about where this process (or my=20
understanding) might be falling down?

Also, does anyone know why when I sync the camera, I see the addition of=20
TWO distinct devices?:
DEVPATH=3D/devices/pci0000:00/0000:00:1d.1/usb2/2-1/2-1.2    and
DEVPATH=3D/devices/pci0000:00/0000:00:1d.1/usb2/2-1/2-1.2/2-1.2:1.0

Thanks,
Christian
