NM doesn't autoconnect USB modem and doesn't show the connection for a long time after disconnect

[Vladimir Kooznetsov]

Not only auto connect doesn't work but also I can't make my usb-stick modem work from the first attempt.
Having this issue since oneiric and still no luck. After the connection breaks it takes a while till it reappears in the applet's menu.

Well, yes, autoconnect doesn't work well.

As for the time it takes to show up in the menu after a disconnection, it's most likely due to the type of device and it needing to be reinitialized in this case, and maybe even modeswitched again.

Can you provide more information, such as debug logs for ModemManager (see http://wiki.ubuntu.com/DebuggingNetworkManager) and what vendor, model is for your mobile device? The output of lsusb is especially useful there.

This bug also affects me. Im using Nokia CS-17 modem with Ubuntu 12.04. It was working nicely on older Ubuntu (last without unity). Now i have to eject /dev/sr1 before modem is found.
