Subject: Problem getting udev to see Kodak camera?

Hey guys,

I've got a Kodak EasyShare DX6490, hooked up to my Toshiba P25-S507 
laptop. I'm running Debian Sarge with their 2.6.8-1 kernel and I've 
installed Sarge's udev package (version 046).

I can't get my udev rules to show my camera in the /dev filesystem, and 
I'm concerned about the results of a test I ran. Anyone mind commenting? ...

After hitting the camera's base-station's "sync" button, I ran 'dmesg' 
and got this output:

    usb 3-1.2: new full speed USB device using address 5
    usb 3-1.2: USB disconnect, address 5

So then I ran this command with the following results:

    pascal:/sys/bus/usb/devices# udevinfo -p 
/sys/devices/pci0000:00/0000:00:1d.1/usb3/3-1/3-1.2/3-1.2:1.0 -a

udevinfo starts with the device the node belongs to and then walks up the
device chain, to print for every device found, all possibly useful 
attributes
in the udev key format.
Only attributes within one device section may be used together in one rule,
to match the device for which the node will be created.

   looking at class device 
'/sys/devices/pci0000:00/0000:00:1d.1/usb3/3-1/3-1.2/3-1.2:1.0':
     SYSFS{bAlternateSetting}=" 0"
     SYSFS{bInterfaceClass}="06"
     SYSFS{bInterfaceNumber}="00"
     SYSFS{bInterfaceProtocol}="01"
     SYSFS{bInterfaceSubClass}="01"
     SYSFS{bNumEndpoints}="03"
     SYSFS{detach_state}="0"
     SYSFS{iInterface}="00"



What concerns me is that I don't see any "BUS" or "ID" line, like I see 
in various examples such as shown here:
   http://webpages.charter.net/decibelshelp/LinuxHelp_UDEVPrimerMisc.html

Could the omission of those two lines from 'udevinfo's output indicate a 
problem?


Also, is there some good way I can trace through what udev does when I 
hit the camera's sync button?  It's apparent that my rule isn't getting 
triggered:
    SYSFS{manufacturer}="Eastman Kodak Company",\
    SYSFS{serial}="KCTCT42820593", NAME="%k", SYMLINK="/dev/my-camera"
and I'd like to figure out where the process is falling down.

Thanks,
Christian
