Permanently change ownership of loop devices

Question

How could I let normal user become the owner of the loop devices?

I tried with chown, but whenever the device is being detached with losetup -d if afterward being created then again automatically owned by root. How can I permanently change the ownership?

I'm using Slackware 13.1.

Use udev rules. However, on my system the group is set to disk, and you just have to add a user to the disk group to use it. I'm not sure if Ubuntu works this way, but you can check.
