mount usb with the wrong user

Hello

I installed trinity on a PC running Ubuntu Lucid (I did not do the original installation so I am not sure if something went wrong)

However when I connect in kde3 an usb device with a linux partion 2 things happen

- the kde daemon pops up twice instead of only once

- the device is mounted but the files belong to another user of this PC. This is very annoying because in order to copy I have to use sudo and then later the chown chgrp command.

I looked up the fstab file in /etc but there I can't see the source of the problem.
