Ah, heh.

Your distro is probably using the usb nodes under /proc/bus/usb which 
have hardcoded ownership of root:root.

I'm not sure how many distros beside Gentoo have switched, however the 
new way is for USB raw access nodes to be placed under /dev/bus/usb. 
This means that they are managed by udev, which is usually configured to 
set group ownership of such nodes to "usb". On my system I just have to 
be in the usb group for everything to work.

Nice, thanks for the success report. I think you're the first person to 
have tested it with a graphical login manager.
