[OpenWrt-Devel] [PATCH] comgt: add ncm proto support

[Sami Olmari]

Well this is what John told me:

"try /dev/cdc-wdm0 as a device or simply do

config interface
option proto wwan
option apn opengate

the new wwan proto will automagically detect your needed prot and device"


I had also tried this and variations, but same resuls:

config interface 'wan'
        option proto 'ncm'
        option apn 'opengate'
        option device '/dev/ttyUSB1'
