Hello,
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.

I have a /etc/udev/rules.d/99-local.rules which contains:
KERNEL=="tty[A-Z]*", GROUP="dialout", MODE="0666"

Thanks James, That did the trick - I had a similar rule but had munged it in copying it from my browser.
