usb floppy

[dr1445]

greetings forum,
the external usb floppy works with gnome but will not start with kde. seems to be an fstab/mstab problem. here is the fstab file,
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
# /dev/hda1
UUID=5b0d0d00-0d48-4dc2-8882-029ba582dcb1 / ext3 defaults,errors=remount-ro 0 1
# /dev/hda5
UUID=0d55b38b-00cf-45f4-bd7a-694e5fc7c827 none swap sw 0 0
/dev/hdc /media/cdrom0 udf,iso9660 user,noauto 0 0

what line should i add to get the device working?
regards
dave
