[LAU] how to mount usb-stick properly

hi list, i am just about to set up the mechanism for being able to mount an usb-stick/hd as a ordinary user. up to now, i was that much successful, that i am able to mount as user, but i cannot write on it as user. this is how the /etc/fstab line looks like: /dev/sda1 /media/usb auto rw,user,noauto 0 0 while mounted, /etc/mtab shows: /dev/sda1 /media/usb ext3 rw,noexec,nosuid,nodev,user=nowhiskey 0 0 but if i try to move a file to usb-stick: nowhiskey@murija2:~$ cp diverses/acpi01 /media/usb/ cp: reguläre Datei »/media/usb/acpi01« kann nicht angelegt werden: Keine Berechtigung nowhiskey@murija2:~$ ...which means "regular file ....could not be set: no permissions does anyone knows the hint, what i should do different to get this to work? any help would be really good, since reading the manuals did not helped here in this problem. cheers, doc
