    Hello, I have problems with usb 4g lte modem on Sbibby 114 build on RT-AC66U
    My actions:

    case A)
    - router is cold booted.
    - plug in modem
    Code:

    - type in console:
    - modprobe mii
    - modprobe usbnet
    - modprobe cdc_ether
    and connection to router lost (network cable unplugged message) but leds are blinking... after few seconds router goes to reboot

    case B)
    - plug in modem
    - power up router
    - type in console:
    - modprobe mii
    - modprobe usbnet
    - modprobe cdc_ether

    router immediately goes to reboot....

    case C)
    write into INIT script
    - modprobe mii
    - modprobe usbnet
    - modprobe cdc_ether
    - plug in modem
    - reboot

    completely nothing
    lsmod shows Bus 001 Device 006: ID 1076:8002
    instead of Bus 001 Device 006: ID 1076:8003

    if I plug this modem to PC with ubuntu - it works...

    case D)
    - modules are loaded from INIT script
    - router booted
    - plug in modem
    - crash...

    once I has happy here is crash log:
