Thanks, Those are default permissions. However those normally won't give a normal user access. You can change the permissions of that file/device to enable your user to have access. I am typing this on my mobile and can't quickly tell you how to do that on a permanent basis. But for a quick change you can use 'chown' to change the owner to your own user. -- Joost -- Sent from my Android phone with K-9 Mail. Please excuse my brevity.

What about 'gpasswd -a user tty' to add the tty group to the user? Needs a re-login to make use of the changes. Wonko

Sounds like policykit, then. Someone with policykit experience might be able to tell us how to ask the system which privileges are required to access that file, and then how to ask the system to give those privileges to a given user. (Not knowing much about policykit, but knowing some of what it's capable of, this would be something I'd like to hear.) -- :wq
