question about kde handling of usb key insertion

[Ernest jw ter Kuile <ejwtk05@xs4all.nl>]

People,

I just inserted my usb key in de usb port. Before I could do anything about it 
(like change to root and mount by hand), this generated a brave attempt in 
kde to do something with this new drive (Surprised!).

However after having answerd the question about what I wanted to do with the 
event (open in konqueror) I got an error popup: 

Could not mount device.
The reported error was:
mount: can't find /dev/sda1 in /etc/fstab or /etc/mtab

Which to me, as an old time unix user, is quite logical if I have never 
inserted anything like it before (so there would not have been any reference 
to a /dev/sda1 until now in fstab).

Now that I saw the question popup like it did just before, I suspect that that 
this specifiek mount should have succeded. I'm just not sure what I should 
change in my Debian or kde install to allow this to happen.

Can somebody give me any advies about what configuration I should change to 
allow users to automount this kind of never before mounted drives 
automatically in KDE ? 

As the question came from kde, I think the configuration is hidden in there 
somewhere. But this could also be some other configuration section (after 
all, as far as I know, you must still be root to mount anything not in fstab)

Also I suspect the configuration change I should have done does not involve  
something like adding all the possible /dev/sda, b, c, d,  1,2,3,4,5,... 
to /etc/fstab. Or should It ?

thanks,

Ernest.
