Thanks for the reply Gareth

you mean adduser to the modems group by:

sudo adduser notandi plugdev (notandi is my username)

and then exit terminal and start again.

I tried that but without any luck. still the same error.

regards Arni

Hi Arni,

Sorry, came up against this exact issue recently on a fresh Ubuntu 12.04
but forgot to tell you!
You need to add your user to the modems group, then log out and in again.

Cheers,
Gareth
