被检测为调制解调器后无法通过 Airtel 3G USB Dongle 建立连接

我能够使用相同的加密狗连接到 Fedora 23 并浏览互联网。加密狗型号为华为 E1731

在 ubuntu 16.04 上，即使检测到 USB 加密狗，也无法建立连接。通过lsusb我得到以下结果

ID 12d1:1446 Huawei Technologies Co., Ltd. Broadband stick (modem on)

通过nmcli con输出是

Airtel01                 5942e4c0-80c0-4f6b-825e-8e8b41185266  gsm              --

当拨号通过sudo wvdial输出

sudo wvdial
--> WvDial: Internet dialer version 1.61
--> Cannot open /dev/ttyUSB0: No such file or directory
--> Cannot open /dev/ttyUSB0: No such file or directory
--> Cannot open /dev/ttyUSB0: No such file or directory

并且连接失败。

我的wvdial.conf内容是

[Dialer Defaults]
        Modem = /dev/ttyUSB0
        ISDN = 0
        Modem Type = Analog Modem
        Baud = 460800
        Init1 = ATX3
        Init2 = AT&F Q0 V1 E0 S0=0 &C1 &D2 +FCLASS=0
        Init3 = at+cgdcont=1,"IP","airtelgprs.com"
        Phone = *99#
        Dial Attempts = 5
        Stupid Mode = on
        Dial Command = ATDT
        Idle Seconds = 7200
        Ask Passwords = 0
        Password = { }
        Username = { }
        Carrier Check = on
        New PPPD = 1
        Auto DNS = on

我尝试切换到调制解调器模式。命令的输出cat /etc/usb_modeswitch.d/12d1\:1446是

Huawei E173s
