FS#3351 - 3g usb modems completely broken on 19.07, patch available on master branch

== Device problem occurs on

Any device using 3g usb modems

== Steps to reproduce

My modem not works after reboot, in LuCI i get “Error: Network device is not present” In logs:

Sat Jan 25 23:00:37 2020 daemon.notice netifd: Interface ‘ppp0’ is setting up now
Sat Jan 25 23:00:40 2020 daemon.notice netifd: Interface ‘ppp0’ is now down

When i click “restart” on ppp0 - nothing happens and no any logs in logread.

But all needed ttyUSB’s exists:

root@OpenWrt:~# ls /dev/ttyUSB*
/dev/ttyUSB0 /dev/ttyUSB1 /dev/ttyUSB2 /dev/ttyUSB3
