Till, Thanks for the comment. The other suggestion is to use lp.plugdev But the downside of that is there is then no way to distinguish between plugged in printers and other devices such as cameras.
So the group ownership of a newly appearing device file is used to determine the type of plugged device (at least by certain apps)?
Do you agree that using scanner is causing confusion for users who just wan't to use hp-toolbox and others?
Yes, I think so. Therefore a desktop peripheral group would be the best solution.
Has Ubuntu worked around this by using hal instead of udev?
They set ACLs for the device files. These ACLs grant access to the user who is currently logged in on the desktop. They are set and removed by log in and log out, probably via PAM.
