external dvd writer and KDE prompt to mount a disc in it

[H.S.]

Hello,

On a Debian Etch system, running 2.6.16 kernel, if I connect an external 
USB DVD writer (Samsung, SE-S164L), I see in /var/log/syslog:
Sep  5 22:54:49 localhost kernel: usb 1-1: new full speed USB device 
using uhci_hcd and address 12
Sep  5 22:54:49 localhost kernel: usb 1-1: configuration #1 chosen from

Storage devices

y to work correctly. Don't use it.


which means that it is detected and given a device name of /dev/sr0. If 
I open k3b, it shows the external writer in its list of optical devices 
(although "cdrecord -scanbus dev=ATAPI" does not list the external 
writer -- due to ATAPI?).


However, if I put in a CD or DVD with data on it, KDE does not give me a 
message window asking what to do with the disk (as it does if I put in a 
disc in an internal writer or reader).

My USB sticks get mounted, cameras get mounted, but a disc with data in 
the external dvd writer does not get mounted. What am I missing here?

thanks,
->HS
