Comment 4 for bug 374755

NetworkManager used to detect most phones I connected to my PC, so I could use them as Mobile Broadband modems. But today, after updating the system, they are not recognized by NetworkManager anymore. The kernel detects the device correctly and ttyACM0 is added. I can communicate with the phones using AT commands without problem.
