The USB permission questions under Linux also constantly pop
up in the libusb mailing list. It is kind of a moving target. Simple
rules like the above should work as always (make sure your username
belongs to the plugdev group).
Sme more advanced rules can help as well -- eg: using udev-acl
and ConsoleKit. The rule tests the availability of udev-acl
and ConsoleKit and uses them if avaibale. If not, it falls
back to group (plugdev) based access control.

Things changes quite often though, last time it was Hotplug,
then comes udev, then there was udev+PAM, HAL+PolicyKit, etc.
Now udev-acl+ConsoleKit seem to be the "State of the Art".
