USB Device Permissions In Fedora 11

I have gotten in the habit of baking a backup of my Blackberry with the 
barry program in Fedora 11. Each time I connect my Blackberry to a USB 
port, some device

/dev/bus/usb/[bus]/[device]

is created. For example

/dev/bus/usb/006/003

However, barry does not work for me (as an unprivileged user) unless I first become root and chmod the device like this:

chmod a+rwx /dev/bus/usb/006/003

Having to do this chmod step annoys me. Is there some way to automate the detection and setting of permissions on the device such that everything is done correctly a moment or so after I connect the Blackberry over USB?

I don't pretend to know the details of how USB devices are assigned, and can always learn more.

I am keeping a Bugzilla item updated with my barry adventures:

Advice welcome.

Bob
