I have an older Sierra Wireless USConnect Mercury 3g modem with AT&T service which is provided for me my one of my clients. As far as I know there is no login information required for it. I got it to work under 10.04 by adding the following entry to /usr/share/hal/fdi/information/10freedesktop/10-modem.fdi
When I connect it to 12.04 the network manager recognizes it but wants me to provide login information which I don't have. How can I get this modem to work under 12.04 without providing login information?
