It should be a symlink, right? What is the link pointing to?

Too many 'l' there :)

Why not? What device file did you create?
And that sounds like your problem right there, you are matching on the
wrong thing in your udev rule.
Actually, you should not need to do _any_ of this, your system should
handle the control of the usb devices properly and give the local logged
in user access to them, no udev rules required at all.
If this isn't happening, it's a bug in your distro.
And yeah, I know you are using Intel's Moblin images, turns out they
haven't implemented this yet, go bug them about it if you care :)
good luck,
