[CentOS] set perms on ttyUSB

CentOS 6.2.

I have spent all morning googling and trying different things to get the permissions
on my ttyUSB0 port set correctly using udev. I am at my wits end. Why is this so convoluted!?

I would really appreciate it if someone could tell me how to do this.

The default permissions come up 660 root,dialout. I have tried adding myself
to group dialout but still get permission denied when I run minicom. The only
thing that works is sudo -i then chmod 666 /dev/ttyUSB0.

Thanks in advance.
