I realized that my scsi devices were like this:

werewolf:~# lsscsi
[0:0:0:0]    cd/dvd  HL-DT-ST DVDRAM GSA-H10N  JL10  /dev/.tmp-11-0
[0:0:1:0]    disk    IOMEGA   ZIP 250          51.G  /dev/sda
[1:0:0:0]    disk    ATA      ST3120022A       3.06  /dev/sdb
[1:0:1:0]    cd/dvd  TOSHIBA  DVD-ROM SD-M1712 1004  /dev/.tmp-11-1
[2:0:0:0]    disk    ATA      ST3200822AS      3.01  /dev/sdc
[7:0:0:0]    disk    LG       USBDrive         1100  /dev/sdd

After a service udev force-reload:

werewolf:~# lsscsi
[0:0:0:0]    cd/dvd  HL-DT-ST DVDRAM GSA-H10N  JL10  /dev/sr0
[0:0:1:0]    disk    IOMEGA   ZIP 250          51.G  /dev/sda
[1:0:0:0]    disk    ATA      ST3120022A       3.06  /dev/sdb
[1:0:1:0]    cd/dvd  TOSHIBA  DVD-ROM SD-M1712 1004  /dev/sr1
[2:0:0:0]    disk    ATA      ST3200822AS      3.01  /dev/sdc
[7:0:0:0]    disk    LG       USBDrive         1100  /dev/sdd

If I insert a disc in /dev/sr1 and eject it:

werewolf:~# lsscsi
[0:0:0:0]    cd/dvd  HL-DT-ST DVDRAM GSA-H10N  JL10  /dev/sr0
[0:0:1:0]    disk    IOMEGA   ZIP 250          51.G  /dev/sda
[1:0:0:0]    disk    ATA      ST3120022A       3.06  /dev/sdb
[1:0:1:0]    cd/dvd  TOSHIBA  DVD-ROM SD-M1712 1004  /dev/.tmp-11-1
[2:0:0:0]    disk    ATA      ST3200822AS      3.01  /dev/sdc
[7:0:0:0]    disk    LG       USBDrive         1100  /dev/sdd

If I reload the disc in the TOSHIBA, it is automounted but the strange
device is still there.

Trying with /dev/sr0 still gives no events. What is happening here ?
It is the kernel or is udev setup ?

TIA
