Лицемер.

Я и не говорил, что ни чего не делал.

Короче, по какому-то приколу usb_modeswitch перестала переключать свисток в режим модема. Я добавил в файл leafpad /etc/usb_modeswitch.conf следующие:

# Huawei E150
# Use device /dev/ttyUSB0 for connecting 
DefaultVendor= 0x12d1
DefaultProduct= 0x1446
MessageContent="55534243000000000000000000000011060000000000000000000000000000"
MessageEndpoint=0x01
CheckSuccess=5

Потом перечитал конфиг: 

# usb_modeswitch -c /etc/usb_modeswitch.conf
Note: No target parameter given; success check limited
Look for default devices ...
   product ID matched
 Found devices in default mode (1)
Access device 007 on bus 004
Current configuration number is 1
Use interface number 0
Use endpoints 0x01 (out) and 0x81 (in)

USB description data (for identification)
-------------------------
Manufacturer: HUAWEI Technology
     Product: HUAWEI Mobile
  Serial No.: not provided
-------------------------
Looking for active driver ...
 OK, driver detached
Set up interface 0
Use endpoint 0x01 for message sending ...
Trying to send message 1 to endpoint 0x01 ...
 OK, message successfully sent
Reset response endpoint 0x81
 Could not reset endpoint (probably harmless): -99
Reset message endpoint 0x01
 Could not reset endpoint (probably harmless): -99
 Device is gone, skip any further commands

Check for mode switch (max. 5 times, once per second) ...
 (For a better success check provide target IDs or class)
 Original device vanished after switching

Mode switch most likely succeeded. Bye!

Рестартовал ModemManager и подключился к сети: 

[root@localhost tux]# systemctl restart ModemManager
[root@localhost tux]# nmcli c up Megafon
Соединение успешно активировано (адрес действующего D-Bus: /org/freedesktop/NetworkManager/ActiveConnection/16)

Посмотрим что будет дальше.
