LEDE cannot create modem interface

System: Onion Omega2s LEDE 17.01 I have connected a Huawei ME90E modem to the USB port of the Omega2s. I have successfully connected the ME906E modem to the Raspberry Pi running Debian, but have problems with the LEDE on the Omega2s. I have tried many times, but still not successful in getting the interface up. I must have missed something. Any help is appreciated. Running ***dmesg*** confirms the modem is recognised: > [ 12.556027] usbserial: USB Serial support registered for GSM modem (1-port) > > [ 12.563783] option 1-1:2.2: GSM modem (1-port) converter detected > > [ 12.570351] usb 1-1: GSM modem (1-port) converter now attached to ttyUSB0 > > [ 12.577378] option 1-1:2.3: GSM modem (1-port) converter detected > > [ 12.583884] usb 1-1: GSM modem (1-port) converter now attached to ttyUSB1 > > [ 12.590910] option 1-1:2.4: GSM modem (1-port) converter detected > > [ 12.597470] usb 1-1: GSM modem (1-port) converter now attached to ttyUSB2 The ports /dev/ttyUSB0, /dev/ttyUSB1 & /dev/ttyUSB2 are created. I run minicom -D /dev/ttyUSB2 115200 to communicate with the modem and I can connect successfully to the system operator's network by running AT^NDISDUP=1,1,"apn" The file /sys/kernel/debug/usb/devices contains T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=480 MxCh= 0 D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 3 P: Vendor=12d1 ProdID=1573 Rev= 2.28 S: Manufacturer=HUAWEI Technology S: Product=HUAWEI Mobile S: SerialNumber=0123456712ABCA17 C: #Ifs= 6 Cfg#= 1 Atr=a0 MxPwr=500mA I: If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.)
